NiCr60/15 vs NiCr80/20 — frequently asked

What is the difference between NiCr60/15 and NiCr80/20?

Nickel Alloy NiCr60/15 and NiCr80/20 are both nickel alloy grades. Both yield at about 390 MPa — strength does not separate them. NiCr60/15 is harder — 170 HB against 160 HB for NiCr80/20 — which matters for wear surfaces and threads.

Which is cheaper, NiCr60/15 or NiCr80/20?

Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which welds better, NiCr60/15 or NiCr80/20?

NiCr80/20. Its weldability rates very good (72/100) against good (65/100) for NiCr60/15.
