Heat treatment is used to enhance the mechanical properties of sand and gravity die castings.
Heat treatment is used to improve the mechanical and physical properties of aluminium castings, primarily to increase the tensile strength and reduce the ductility of the metal.
Heat treatment is carried out in a highly controlled manner in specialised furnaces to ensure that the casting retains its original shape without cracking. The temperature is kept within very strict parameters to ensure that the casting complies with the required specification.
At Haworth Castings, we use various heat treatment conditions to produce the different degrees of hardness required for our castings, namely:
