The metals and alloys listed below are commonly used in woven wire cloth and some types of welded wire mesh. Different alloys and small variations in element content produce a wide range of corrosion, abrasion, and heat resistant characteristics.
PLAIN STEEL C .05 - 1.30% Fe Balance
Relatively low cost, high strength metal for many general applications such as window guards, fireplace screens, and shaker screens. Small variations in carbon content create various desirable property variations.
High carbon content increases resistance to abrasion and impact, making it useful for gravel and stone separating in the mining and coal industries. Galvanizing plain steel wire mesh improves durability and corrosion resistance.
STAINLESS STEEL ALLOYSThe inclusion of chromium and nickel allows steel to become resistant to staining and corrosion. Differing amounts of carbon, chromium and nickel affect the secondary characteristics such as welding and forming.

COPPER Cu 99.9% min
Copper is resistant to atmospheric corrosion, but is attacked by oxidizing agents such as Nitric Acid, Ferric Chloride, Cyanides, and Ammonia Acids compounds. Melts at 1981 F.
BRASS Brass is similar to copper in its resistance to acids, though to a somewhat lesser degree. Like copper, brass is highly susceptible to ammonia and its salts; brass alloys containing zinc in excess of 20% should never be used in their presence because of the resultant de-zincification.

COMMERCIAL BRONZE Cu 90.0% max Zn 10%
This alloy contains 90% Copper and 10% Zinc, and is superior to Low Brass in resistance to corrosion. Its good resistance to atmospheric corrosion makes commercial bronze popular for window screening.
PHOSPHOR BRONZE Cu 94% Sn 4.75% P .25%
Formed of Copper and Tin with a minor addition of phosphorous, this alloy is an auburn color and exhibits physical and anti-corrosive properties slightly superior to those of copper and zinc alloys. Phosphor Bronze can be drawn as fine as 0.0012", has great strength and ductility for weaving and long service, and is resistance to common corrosive agents.
ALUMINUM ALLOYSThese are light metals, with good strength to weight ratios. At ordinary temperatures they resist Nitric and Sulphuric Acids, but corrode quickly in the presence of alkaline solutions and hydrochloric and hydrofluoric acids. Melts at 1218 F.
