MHD is an abbreviation for medium hard drawn copper wire, a copper temper that balances mechanical strength and conductivity between annealed and hard drawn wire.
MHD designates medium hard drawn copper wire, a temper produced by drawing copper to a degree that gives it more strength than soft annealed wire but more flexibility than fully hard drawn wire. This middle temper offers a balance of mechanical strength and workability, with conductivity that remains suitable for many electrical applications.
The temper of copper wire affects both its handling and its performance, since drawing copper increases its strength while slightly reducing its flexibility. Selecting a medium hard drawn temper provides durability for applications that require some mechanical strength without the stiffness of a fully hardened wire, making it a practical compromise.
In commercial and industrial wire, choosing the appropriate copper temper is part of matching a conductor to its application's mechanical and electrical demands. Medium hard drawn wire serves where a balance of strength and conductivity is needed, contributing to reliable performance in the role it is selected for.
Because copper temper affects both handling and durability, selecting a medium hard drawn wire is a way to gain strength without the stiffness of a fully hardened conductor, suiting applications that need a practical balance of the two.
At Windy City Wire, an understanding of conductor characteristics, including copper temper, supports the selection of wire suited to each application. Recognizing how a temper like medium hard drawn balances strength and conductivity helps customers match conductors to their commercial and industrial needs.
