Explosive welding cathode clads

Materials

The typical standard aluminium grade is al1060, al1050. The standard steel is Q235B, 1008. and Copper C11000, T1, T2 is the standard for copper clads. Design ­exibility allows for other material options that ‑t each individual application.

Fabrication

The clads are cut to customers’ required dimensions, +/- 1 millimeter, unless otherwise requested. Typical total thickness for steel cathode clads is 38.1 mm with 12.7 mm of aluminium. Thickness can be customized based on application requirements. Parts can be fabricated in any number of geometries. Custom designs can be produced via our wide array of saws, waterjet and CNC.

Our Advantages:

Electrical

The electrical resistance of a transition insert is nominally the series resistance of the components. There is no resistance increase or electrical conductivity loss associated solely with the bond or bonding process.

Strength

The technology is tensile tested at the bond to exceed the strength of the aluminium. High purity aluminium is typically 85-90 MPa in tensile strength, while the Pyrotek roll-bonded transition insert demonstrates a bond tensile strength of greater than 125 MPa as-rolled.

Temperature

Aluminium-steel inserts can operate safely at elevated temperatures. The parts have been tested per ALCAN – Pechiney AP 18–30 qualifying tests. For the 20°C Tensile test, clads always meet the 150MPa minimum requirement, often exceeding 180MPa. At 500°C , the minimum requirement is 85MPa, Pyrotek clads typically exceed 120MPa. Clads with no interlayer can withstand consistent temperatures up to 400°C. Adding a chromium interlayer allows for operating temperatures up to 500°C.
