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% tin. 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. |
