Phosphor bronze

From Wikipedia, the free encyclopedia

Phosphor bronze is an alloy of copper with 3.5 to 10% of tin and a significant phosphorus content of up to 1%....

These alloys are notable for their toughness, strength, low coefficient of friction, and fine grain. The phosphorus also improves the fluidity of the molten metal and thereby improves the castability, and improves mechanical properties by cleaning up the grain boundaries...

Phosphor bronze is used for springs, bolts and various other items used in situations where resistance to fatigue, wear and chemical corrosion are required...

Grades A, C and E – C51000, 52100, 50700 are commonly used nonferrous spring alloys. The combination of good physical properties, fair electrical conductivity and moderate cost make Phosphor Bronze round, square, flat and special shaped wire desirable for many springs and electrical contacts and a wide variety of wire forms where cost of properties does not prescribe Beryllium copper...

Your customer likes it because it makes tight, strong, corrosion-resistant connections that are also less prone to stress-cracking, creep, and fatigue than ordinary fasteners.

www.keybellevilles.com is one manufacturer, but beware of their healthy minimum quantities and setup fees.

www.sandc.com has, in times past, filled smaller orders for me.
