ASTM F1537, Cobalt Chrome Molybdenum, CCM® Alloy 1

ASTM F1537, Cobalt Chrome Chromium, CCM® Alloy 1
STEELMAX Metal Story

ASTM F1537 규격은 Cobalt-Chromium-Molybdenum 합금입니다.
Co-28Cr-6Mo 라는 화학 조성 식으로도 불립니다.

우수한 내마모성–excellent wear resistance
고강도 — high strength

내식성 — corrosion resistance
생체 적합성– biocompatible 으로

외과용 임플란트– surgical implants 로 사용합니다.
F1537 ASTM 규격은 Chrome-moly 라고도 부르고

Cobalt-Chromium-Molybdenum Alloy 를 줄여서
CCM Alloy 라고도 부릅니다.

CCM® Alloy 는, Carpenter Technology Corporation 의
Trademark 입니다.

F1537 ASTM 규격 재료는, Knee, Hip, Shoulder implants,
Fracture fixation 재료로 사용됩니다.
