|
Phosphor Bronze, C51000 Grade A
 |
The work horse of the non-ferrous spring industry.
|
 |
Good Strength, fair electrical conductivity and a moderate price.
|
 |
Grade A stands between Brass and Beryllium Copper in properties: temperature resistance, fatigue resistance and cost. It gains its spring temper from cold work, and is furnished in whatever temper is appropriate for your application
|
|
Phosphor Bronze C52100 Grade C
 |
Similar non-ferrous spring applications as Grade A.
|
 |
Slightly higher strength with a given formability.
|
 |
Higher Tin content allows Grade C to work-harden faster and thus develop a higher tensile strength with the same degree of cold work
|
|
|
|
Phosphor Bronze, C50700 Grade E
 |
Fair strength, good electrical conductivity at an economical price.
|
 |
No Zinc to cause de-zincafication.
|
 |
Better conductivity than the Brasses. A better alloy for hot solder or hot tin coating.
