Unified manufacturers a complete line of abrasion and impact resistant screens designed for heavy duty industrial screening applications.

Wire cloth can be manufactured from any metal or alloy than can be drawn into wire that is suitable for weaving.

Industrial requirements to meet specific applications has resulted in the development of a broad spectrum of wire cloth materials. Each type of material has its own distinct properties that affect its performance in the particular application.

The selection of the material is dependent on the intended usage and consideration of various factors including:

(A) The final application of the wire cloth pertaining to requirements of strength, abrasion resistance, chemical resistance, corrosion resistance, heat resistance or the suitability for use in food production etc.

(B) Secondary processing such as suitability for forming, welding, heat treating or the application of coatings.

The most commonly utilized materials in wire cloth weaving are listed here for reference purposes.

AGGREGATE & MINING STEEL CHOICES
High Carbon
High Carbon hard drawn steel is used when resistance to abrasion and impact is required. This material is commonly utilized in agriculture, coal, gravel, mining, sand and stone separating, sizing and sorting applications
Tufflex
Tufflex is a substitute for Oil Tempered wire, with greater ductility (flexibility) and tensile strength. In certain applications Tufflex wire has proven to last almost two times as long as Oil Tempered wire.
Oil Tempered
Oil Tempered wire is specially tempered high carbon steel wire to provide greater strength and abrasion resistance, although its resistance to impact is somewhat lower than regular high carbon steel.
Type 304

Typical applications include use with chemicals, food products, pharmaceuticals and exposure to moisture.

Unified has hundreds of specifications in stock, and we manufacture thousands of various designed specifications. Screens can be ordered by Square Opening or Mesh Count. The square openings are produced with a locking precrimped weave to insure accurate openings throughout the life of the screen.

Wire square opening space cloth is specified by the size of the opening or "space" between the wires.

Wire Cloth has one of the largest selections of weave styles available. More weave selection means better designs for special needs.. aggregate production, mineral sizing, grain drying, traveling water screens, power plant applications, livestock flooring and many others. Select from the weaves shown here or call your Unified Rep in your area for information on special fabricated screens.

Long Slots Tri-Mesh

All the advantages of Tri-Loc weave with Loc-Crimp in one direction and Dbl-Crimp in the other.

l

Slotted Screens utilize a locking weave to maintain accurate screen openings. Slotted openings reduce blinding and increase screening efficiency due to the enhanced screen open area.

Wire slotted screens have a locking weave to hold accurate screen openings.

The long slots give more efficient, even flow when blinding is a problem. A larger percentage of open area gives effective screening of bulky, sticky or wet material.

Most specifications are in-stock and available for prompt delivery.

Clean Screens are high quality, non-blinding screening surfaces made from crimped wire. Clean screens provide accurate screening and sizing, by separating the flakes, elongated material, and slivers from product where other screens fail. Flowmax Clean Screens are high quality, non-blinding screening surfaces made
from crimped wire. Clean screens provide accurate screening and sizing, by separating the flakes, elongated material, and slivers from product where other screens fail.

Flowmax Clean Screens have a larger percentage of open area than square opening woven mesh, thus giving higher production rates. Clean Screens can be hooked with any edge style to fit all screening equipment, stationary or portable.

W-Openings

W opening Clean Screens have combinations of different wire diameter sizes. The different wires vibrate at varying speeds and produce a self cleaning surface or a non-blinding, non-plugging screen.

The information and data presented herein are the typical or average values and are not a guarantee of maximum or minimum values. Applications specifically suggested for material herein are made solely for the purpose of illustration to enable the reader to make his own evaluation and are not intended as warranties, either express or implied, of fitness for these or other purposes.
Type 304
Typical applications include use with chemicals, food products, pharmaceuticals and exposure to moisture.
Type 309
A heat resistant alloy (23% chromium, 12% nickel) which is useful in temperatures up to 1700 Degrees Fahrenheit.
Type 316
Wire cloth woven of T-316 has extensive use in chemical processing when better corrosion resistance is required than the regular chromium-nickel types.
Type 317
Similar to the basic alloy (18% chromium) but with a higher nickel (14%) and molybdenum (3%) content for increased corrosion resistance.
INDUSTRIAL MAGNETIC ALLOYS
Type 410
Type 410 possesses mild corrosion resistance as well as heat and oxidation resistance up to 1400 Fahrenheit.
Type 430
T-430 is not heat treatable but is more resistant to chemical attack and high temperature than T-410.
COPPER AND COPPER ALLOYS
Copper

Copper offers excellent electrical and thermal conductivity. It is non-magnetic, anti-sparking and is resistant to atmospheric corrosion, salt air and brine.

Copper applications are limited due to its low tensile strength, poor resistance to abrasion and common acids
Brass
High brass (70% copper, 30% zinc) and low brass (80% copper, 20% zinc) have much better abrasion resistance, better corrosion resistance and lower electrical conductivity when compared to copper.
Bronze
Superior to low brass in resistance to corrosion, this alloy contains 90% copper and 10% zinc. The combination of lower tensile strength and better formability when compared to brass make bronze a popular alloy for window screening.
Phosphor Bronze

This copper-tin (4% to 9% tin, approximately 0.25% phosphorous with the balance copper) alloy is corrosion, wear and tear resistant was frequently used in the past for fine mesh cloth.

Phosphor Bronze is not suitable for exposure to hydrochloric acid or strong oxidizing agents.

ALUMINUM AND ALUMINUM ALLOYS
1100

Pure Aluminum in the woven form is typically used where its light weight and corrosion resistance is more important than strength.
5056
Containing magnesium, manganese and chromium, this non-heat treatable alloy is used most often for weaving wire cloth. 5056 contains 5% magnesium providing good corrosion resistance (particularly in marine atmospheres) and greater strength.
ALCLAD 5056
The wire has a core of 5056 Aluminum encased in pure Aluminum, a combination providing both strength and corrosion resistance.

NICKEL AND NICKEL ALLOYS
Nickel

Nickel is noted for its corrosion resistance, good electrical conductivity and high heat-transfer properties. Wire mesh woven of nickel is used in pure food and drug processing among several other applications although nickel wire cloth is replaced frequently with stainless steel.

Monel 400
This alloy contains approximately 67% nickel, 28% copper and 5% other elements. It is essentially non-corrodible. Monel is more resistant to oxidation than copper and more resistant to reducing conditions than nickel.
Hastelloy B
This alloy is recommended for corrosion resistance to hydrochloric acid although it is usually not used for high temperature applications.
Hastelloy C
Offering good corrosion resistance to strong oxidizing agents, this alloy performs well at elevated temperatures in the range of 1600 to 1800 Fahrenheit.
Inconel 600
This alloy is high in nickel content (76% to 80%), combined with a chromium content of 14% to 16% is suitable high temperature applications where resistance to corrosion is required. Inconel is the preferred material for heat-treating baskets fabricated of woven wire cloth.
Inconel 800
Similar to T-330 stainless steel, Inconel has superior corrosion resistance and strength
Nichrome I
A high nickel (60%) alloy containing 16% chromium and 24% iron suitable for certain chemical conditions and for temperatures up to 1700 Fahrenheit.
Nichrome V
A higher nickel chromium alloy containing 80% nickel, 20% chromium, this material is suitable for severe chemical conditions and for elevated temperatures up to 2000Fahrenheit.

OTHER METALS
Rare metals such as columbium, gold, molybdenum, platinum, titanium and tungsten can be provided as specified.
