We use supreme-grade quality bronze, phosphorous, sand & various other alloys as well as non-ferrous alloys such as Tin, Leaded Gun Metal & lead for making these casting so as to cater to the demands of various industries. Our Phosphorous Bronze Castings are acclaimed by customers for their dimensional accuracy, sturdy construction and zero maintenance.

Phosphor Bronze (sometimes sold with the shorter name Phos Bronze or P B Casting) is an alloy of copper with 3.5 to 10% of tin and a significant phosphorus content of up to 1%. The phosphorus is added as deoxidizing agent during melting. 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.

Applications:
Phosphor Bronze (94.8% copper, 5% tin, 0.2% phosphorus) is also used in cryogenics. In this case its combination of fair electrical conductivity, and low thermal conductivity allows the making of electrical connections to devices at ultra low temperatures without adding excessive heat.

Phosphor bronze is used for springs, bolts and various other items used in situations where resistance to fatigue, wear and chemical corrosion are required (e.g., a ship's propellers in a marine environment). The alloy is also used in some dental bridges.

The names describe variations in formability caused by cold rolling. Tests have shown that the new C66300 alloy is more formable, even in bad way orientations, than veteran alloys C51000, C51100 and C52100.
