Clad strips

Brief description

By joining different materials with different properties it is possible to manufacture, or even develop deliberately new materials with new properties.

This is a long-established process. About 2,500 years ago the so-called DAMASCUS STEEL BLADES were produced in the Orient. The two steel qualities used in production (soft easily formable iron and hard brittle iron) were joined firmly together by forging. The famous DAMASK PATTERN was achieved by multiple folding, intermediate annealing, and hammering.

Industrial processes for the manufacture of clad materials are cast cladding, hot roll bonding, press bonding, cold roll bonding, and explosion bonding. The company Auerhammer Metallwerk GmbH has exclusively used cold roll bonding on a large scale since 1984.

 In addition to the product group of thermostatic bimetals AMW also produces:

Strips out of soft unalloyed steel

• Copper-clad:

  Main application as conductor rails in the electrical industry (automatic circuit breakers, protective motor switches etc.)

• Brass-plated:

  Application as brush holder for electric motors, as coin blanks and plain bearings in combustion engines

• Tombac-plated:

  Cups for bullets

• Nickel-plated:

  Main application as coin blanks

Strips out of stainless steels

• Copper-clad:

  Main application as heat exchanger, cooler

• Nickel-plated:

  Spring elements in lamp production

Special cladding layers

Examples:

• CuSn6 on stainless steel as soldering foil
• CuZn20Ni5 on nickel as 2 Euro core strip
• CuNi25 on nickel as 1 Euro core strip
• CuZn20Ni5 out of CuNi25 as medal strip
• Nickel on SE-CU as electrode for high-performance spark plugs

• SI - Units
• in.-lb Units
