CuSn10

A cast tin bronze with about 10 % tin. It offers a balanced combination of wear resistance, toughness and corrosion resistance, including resistance to seawater. Used for bushes and bearings at moderate loads and sliding speeds, gears, pump and valve parts and impellers. It is tougher but somewhat less hard than CuSn12.

Frequently asked questions

What is the difference between 10 % and 12 % tin bronze?

As the tin content increases, hardness and wear resistance rise and ductility falls. CuSn10 is preferred for general-purpose bushes and gears; CuSn12 for worm wheels and heavy-duty bushes subject to higher loads and wear.

What are the designations for CuSn10?

CuSn10: CuSn10-C, EN CC480K, UNS ≈ C90500 / C90700, BS CT1. Any of these designations can be used in your enquiry; we will match the correct material.

Why can the invoiced weight differ from the calculated weight?

The calculator gives the theoretical weight. The actual weight varies with dimensional tolerances and cutting allowance; we invoice on the actual weight as weighed.

What information should I send for a quote?

We only need the size (diameter × length), quantity and delivery location. If you fill in the calculator above, these details are added to the WhatsApp message automatically.
