Solution for Discolored, Brittle Castings

Oct 11, 2022

When investment castings become brittle and are discolored and rough, it is likely the foundry is experiencing issues that require attention. There could be several possible causes for such problems. The quality of the alloy being used could be substandard or defective. An alloy that is too high in sulfides and oxides could cause the problem, especially when using recycled metal. The issues could also occur if the molten alloy is overheated or if the dewaxing temperature is too high. Experienced foundry staff, including an expert metallurgist, have the expertise, equipment, and resources necessary to address and prevent these problems.
