Comparing two suppliers of aluminium alloys for foundry

Abstract

In this time many suppliers are existed with raw material for foundry and the same as a minimum number has difficult task of choosing the most suitable one. How we can search the best of them for us? It is hard question. This article shows what can be checking around the raw material. The basic test is spectral analysis, what is indispensable every foundry in this time. Chemical composition absolutely does not show an important information about properties of alloy. A little bit more tests were made for compare 2 suppliers. There were used measuring as Dichte Index, Thermal analysis and metallographic cuts as necessary evidence for proper evaluation.
