Aluminum Investment Casting

Aluminum investment casting produces complex parts from light, corrosion-resistant alloys. BRK Metal casts aluminum parts to customer drawings, drawing on casting experience since 2002.

Properties of Aluminum

With a density of about 2.7 g/cm³, aluminum weighs about a third as much as steel. Its natural oxide layer gives it good corrosion resistance in many environments.

• Low weight and good specific strength
• Good corrosion resistance
• High thermal and electrical conductivity
• Good machinability
• Recyclability

Aluminum Casting Alloys

A356 (AlSi7Mg) is the aluminum alloy we cast most. It flows well, and heat treatment can raise its strength. We also cast the other aluminum alloys commonly used in investment casting. We select the alloy according to your drawing and the service conditions.

Why Investment Casting for Aluminum?

Investment casting produces thin-walled aluminum parts with internal shapes as one piece. It needs no costly steel die like pressure die casting, so it also suits lower volumes and gives more design freedom. Replacing welded or bolted assemblies with one casting can cut weight and assembly work.

Applications

Aluminum investment castings serve the defense, automotive, machinery and electrical sectors. Housings, covers, brackets and connectors are typical parts.
