AS 1565-1985 C93500
AS 1565-1985 C93500 is an Australian material specification for leaded bronze alloy containing approximately 9% lead and 5% Tin. These additions create an alloy with excellent machining properties, good wear properties, a medium strength and a good corrosion resistance. It will also withstand some weaker acids in contaminated waters.
Suitable for bearings where low to moderate loads are used the as-1565-1985-c93500 is also ideal for applications with little lubrication or possible misalignment for short periods. Also comparable to LB4 and CC494K, this alloy is most suitable for mild steel shafts with low loadings or hard shafts with moderate or low loads and speed.
