Abstract

Powder metallurgy is a mechanical forming process with increasing applicability in the Brazilian industrial scenario. Application fields include, for example, manufacturing of automotive components, home appliances, cutting tools and electric tools. Sintering is the most important phase of the process, in which the already compacted powder is subjected to a temperature below its melting point, obtaining a material with excellent finish, dimensional accuracy and mechanical properties. The present work aims to assess the behavior of aluminum with the addition of 1% Copper, specifically evaluating density, hardness and metallography presented as a function of applied loads on each of the samples was between 100 MPa to 1,000 MPa. The metallography presented porosity inherent in the process, but there was a hardness increase from 40 to 50 HV. Keywords: Powder metallurgy, Aluminum Copper composition, hardness, density and metallography.
