Bimetal bushes are composed of two metal strips, in two different materials; the first layer is normally in steel, the second layer is normally constituted by an alloy containing copper, which when coupled with the steel strip acts as an internal covering. Furthermore,  grooves and grease dots are provided to retain lubricating material and thus reducing extra wear-tear and providing longer life in abnormal working environments.

Bi-metal bushing in laminated spring and shackles are designed to withstand impacts,vibratory loads as well as friction. GJ BUSH bi-metal spring bushes are capable to withstand these loads.
