Heat treatment | FINALCAST, s.r.o.

Increased mechanical properties of castings are reached by means of heat treatment. The heat treatment is a process of altering material properties by means of heating. The temperature must have exactly specified and controlled value and time path. The purpose of the heat treatment of the aluminum alloys is to improve the mechanical properties and to eliminate the inner stress in the casting. The less frequent purpose of the heat treatment is stabilization of the casting dimensions.

Heat treatment procedure:

Annealing
Quenching
Hardening

Apart from heat treatment of our products we are offering this operation also to external companies as a separate service. The heat treatment process is certified according to ISO 9001:2008, OHSAS 18001:2007 and ISO 14001:2004.
