Metal Testing

AFW has numerous metallurgical process controls in place for improved and consistent mechanical properties.

Anytime new metal additions are made in the melting process, a sample is taken and tested in our Quality Assurance Lab. This is done using our spectrometer which gives us the chemistry reading of up to 27 different elements. We can test either aluminum or brass/bronze and the results are stored for a period of 5 years. By using this latest technology we can immediately certify our material before the castings are ever poured.

Along with testing the chemistry, we have the ability to check the hardness of castings using our Brinell hardness tester.
