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.
