Zamak 5: Strength and Secondary Operations

Zamak 5 is a zinc die-casting alloy distinct from Zamak 3. Material reference.

Strength and Secondary Operations

When considering it for a more highly loaded casting, review the final geometry and secondary operations as well as the alloy comparison. A substitution may affect forming, assembly or finishing assumptions; use the same part-level test to compare the alternatives.

Manufacturing and acceptance checks

Specify the exact alloy and cast dimensions, then mark surfaces requiring machining or coating. Define fastener installation and any press-fit or staking operation. Ask for a first-article assembly test and inspect the finished part after the operations that can alter fit or surface condition.
