Bimetallic strips have excellent technical characteristics when used in structures operating under high load and wear, in corrosive environments, and they are also more economical than their stainless steel counterparts.(//tractor-service.com)
Bimetallic strips consist of two different materials: usually the inner layer is made of corrosion-resistant metals (copper, aluminum, brass, titanium, bronze, zirconium, etc.), and the outer layer is made of stronger ones (stainless steel, carbon steel, titanium). The inner layer provides resistance against general, pitting and pitting corrosion.
