(supersedes all previous editions)
Alleima® F1537 is a cobalt-chromium-molybdenum (CoCrMo) alloy, available with low and high carbon (C) content. Both alloys are characterized by high strength, wear resistance and corrosion resistance.
|Alleima® F1537 (Alloy 1, UNS R31537)||≤ 0.14||26–30||5–7||≤1||≤0.75||≤1||≤1||≤0.25||Bal|
|Alleima® F1537 (Alloy 2, UNS R31538)||0.15–0.35||26–30||5–7||≤1||≤0.75||≤1||≤1||≤0.25||Bal|
CoCrMo alloys are used by customers for joint replacement (hip, knee, shoulder) and fixation devices.
Alleima® F1537 bar is offered in a comprehensive range of standard sizes from 10-80 mm diameter. The bar is supplied in the annealed, hot worked and warm worked conditions with a peeled or ground surface finish.
Bar is delivered in 3.0-3.5 m straight lengths. Shorter lengths are available on request.
