Expansion Alloys

Expansion alloy also known as thermal expansion alloy, widely used in a variety of fields, such as electronics, precision measuring tools, precision instrument and cryogenic engineering. Controlled expansion alloys contract upon heating rather than expanding as most alloys do in negative thermal expansion process, so they have a range of potential applications. Expansion alloys include controlled-expansion alloys, low-expansion alloys and non-magnetic controlled expansion alloys.

Types of Expansion Alloys

Advantage of Expansion Alloys

Beimetal has mastered the high-precision and high-flatness control technology of expanded alloy strips/foils, and solved the difficulties of strip/foil thickness accuracy and plate shape control. Through systematic research, the comprehensive quality of expansion alloy products has been significantly improved, the production capacity has been increasing, and the industrialization of multi-species, multi-specification and multi-purpose expansion alloys has been realized.
