Beryllium Copper wire is an outstanding material as it combines excellent formability with extremely high strength properties once it undergoes the aging process. During aging, the internal structure of the wire is modified, leading to enhanced mechanical characteristics.
When it comes to applications, Beryllium Copper wire is widely used
in various industries. In the field of springs, it provides the
necessary elasticity and durability. Springs made from this wire
can withstand repeated compression and extension without losing
their shape or mechanical integrity.
Moreover, special heat treating of the wire at the mill gives rise
to a “Mill Hardened” (HM) tempered Beryllium Copper wire. This
unique manufacturing process imparts specific mechanical properties
to the wire. Once in this state, the wire can be easily formed into
the desired shape through processes like bending, coiling, etc.
