Types of Wire for MINIMESH® Filter Cloth Products

Copper Alloys

COPPER has some favorable corrosion resistant properties, but its relatively low tensile strength and high ductility limit its application and a Copper alloy is therefore usually preferred for wire cloth. Commercial or Pure Copper is sometimes used for its electrical properties.

BRASS, Tyler Special Composition Brass (Cu 85%, Zn 15%) wire cloth is the preferred Brass alloy for applications where non-rusting material is needed but COMMON BRONZE is a higher copper alloy (Cu 90%, Zn 10%) used in cases where a little better corrosion resistance is required than that of Brass.

PHOSPHOR BRONZES are high copper alloys containing from 4% to 9% tin, about 1/4% Phosphorous with the balance Copper. These alloys have proved very valuable in a wide range of screening, conveying and filtering problems. In addition to its corrosion resisting qualities, the physical properties of Phosphor Bronze make it an ideal metal for weaving. Phosphor Bronze is much stronger and tougher than Brass and its ability to withstand cold working makes it the outstanding metal for Fourdrinier Wires.

Nickel alloys

NICKEL 200 is used for certain food products and to resist some chemicals such as caustics, some organic acids, and many other corrosive products.

MONEL (1) alloy 400, a high nickel copper alloy, is one of the most widely used alloys for corrosion resistance. It has the strength of mild steel and will not corrode in a great many solutions met with industrial applications. Both Monel and Nickel are used for Food Products where sanitary service is important.

Stainless steels

Stainless Steels demonstrate longer life under severe corrosive and temperature conditions. The principal Stainless Steel used for woven wire cloth are:

TYPE 304 is the basic stainless alloy (18% Chrome. 8% Nickel) and is most extensively used to weave wire cloth. It has excellent corrosion resistance satisfactory for most applications. Where no specific type is specified, it is assumed that Type 300 is acceptable.

TYPE 304 L is the same as above except with extra low carbon content to permit welding.

TYPE 316 is the basic 18-8 analysis stabilized by the addition of Molybdenum for increased resistance to chemical corrosion. Type 316 Stainless Steel is used in bleach solutions where the hydrochloric acid content does not exceed 2%.

TYPE 347 is the basic 18-8 alloy, modified by the addition of Columbium for stabilization of steel within the critical range of 800 to 1500°F. It is used where the cloth is to be welded.

TYPE 430 is a straight Chromium alloy without Nickel possessing a high degree of resistance to chemical and atmospheric corrosion and oxidation up to 1600°F.

Other Types of Stainless Steels for Special Conditions are as follows:

TYPE 309 is a Chrome-Nickel alloy (Cr 25%, Ni 12%) developed for increased heat resistance over the basic Type 304 analysis but not equal to the high Nickel alloys.

TYPE 317 is the basic alloy furnished with higher Chromium and Molybdenum content than Type 316 for increased corrosion resistance (Cr 18%, Ni 14%. Mo 3-4%).

TYPE 318 is an improved modification of the basic 18-8 alloy with the addition of Molybdenum and Columbium for stabilization of the steel within the critical range of 800 to 1500°F. and to improve its qualities of resistance to corrosion and oxidation. This type combines the qualities of both Types 316 and 347.

TYPE 330 is a Nickel-Chromium alloy used mostly for heat treating baskets and fixtures for temperatures up to 1650°F. (Cr 15%, Ni 35%). See Incoloy in the Heat Resisting Alloys Croup.

TYPE 446—A high Chromium steel without Nickel possessing excellent resistance to chemical corrosion and oxidation up to 2000°F.

TYPE 310 is a high-temperature Chrome-Nickel alloy (Cr 25%, Ni 20%) similar to Type 309 but more stable due to its higher Nickel content.

TYPE 317 L Is the same as above except with extra low carbon content to permit welding.

TYPE 321 is the same as Type 347, except for the addition of Titanium instead of Columbium.

TYPE 410 is a straight Chromium alloy without Nickel possessing excellent resistance to corrosion and oxidation butnot as generally used for wire cloth as Type 430.

TYPES 501 and 502 are low Chromium alloys without Nickel possessing characteristics between carbon steel and regular Stainless Steels.

Heat resisting alloys

TY-CHROME 1 is a high Nickel Chromium alloy (Ni 60%, Cr 16%, Fe 24%) used for certain chemical conditions and for temperatures up to approximately 1700°F. Approximate equivalents are Nichrome (2), Tophet C (7) and Chromel (8).

INCONEL (1) alloy 600 is a high Nickel Chromium alloy (Ni 76.0%, Cr 15.8%, Fe 7.2%) used for corrosion resistance and temperatures up to approximately 1800°F.

N-155 (3) is a Cobalt Nickel Chromium Iron austenitic alloy having high oxidation and scaling resistance along with good high-temperature properties up to 2000°F.

RENE 41 (6) is a Nickel base alloy with exceptionally high strength at temperatures in the range of 1200 to 1800°F.

TY-CHROME 5 is a higher Nickel Chromium alloy than Ty- Chrome 1 (Ni 80%, Cr 20%) used for more severe chemical conditions and for temperatures up to 2000°F. Approximate equivalents are Nichrome V (2), Tophet A (7) and Chromel A (8).

ELGILOY (3) is a Cobalt base alloy containing high percentage of Chromium, Nickel and Iron. It has high fatigue resistance, high tensile strength and good corrosion resistance.

INCOLOY (1) alloy 800 is a Nickel Chromium alloy (Ni 32%, Cr 20.5%, Fe 46%) used mostly for heat treating baskets and fixtures for temperatures up to 1650°F. Approximate equivalents are Type 330 Stainless Steel, Chromax (2) and Alloy 502 (8).

HASTELLOY (3) A, B, C alloys can be supplied for especially severe conditions where heat or special corrosion resistance is required.



Aluminium alloys

1100 ALUMINUM, PURE in woven form is used mostly where its light weight and corrosion resistance is more important than strength.

ALCLAD 5056 (4) wire has a core of 5056 Aluminum encased or clad with pure Aluminum. This combination provides both strength and corrosion resistance.

5056 ALUMINUM — an Aluminum alloy containing magnesium, manganese and chromium. It is designed for greater strength and is the best Aluminum alloy for weaving wire cloth.

Rare metals

Rare metals can be supplied when required including Tantalum, Molybdenum, Silver, Platinum and many others.
