Description

Aluminum DIN 3.1655 is a popular age-hardenable alloy known for its free-machining characteristics and mechanical properties. It can be machined to very close tolerances while still maintaining a smooth and bright finish. Unlike other aluminum alloys, DIN 3.1655 does not offer good corrosion resistance or weldability.
