Continuously increasing engine performance requires correspondingly powerful components – above all the crankshaft. To increase the fatigue strength of its crankshafts, ALFING developed a special induction hardening process and also the equipment to carry it out. As early as 1952 the first induction hardening machine for crankshafts was put into service at ALFING. The advantages for the company are obvious:
Crankshafts which have been partially hardened prior to mounting in the engine are able to give their full capacity from the start. They have excellent fatigue strength, can run at higher speeds, are much more resistant to wear and thus last much longer.
This combination of crankshaft know-how and hardening technology has helped us become the world market leader.
