Explosive cladding is a solid state process in which controlled explosive detonations force two or more metals together at high pressures, resulting a high quality metallurgical bond between the colliding surfaces. The bonding zone of the two metals has a characteristic wave-form.
Due to the high pressure during the explosion and collision of the clad plate (e.g. copper) and the base plate (e.g. aluminium) the two materials get melted and the melted metal spurt goes through the collision zone, which then shuts the two plates together in a unique wave-like shape.
The major advantages of the explosive cladding process in comparison the conventional ones are that bond can be create between normally incompatible metals (e.g. aluminium and steel: Figure 3) and also that there is no practical limit to the ratio of thickness of the metals to be bonded. It is feasible to apply a minimum thickness of the expensive cladding metal on the inexpensive base metal the process requires minimum facilities and tooling.
The company is looking for partners interested in purchasing the know-how or purchasing the raw material (bimetal sheets) which can be later rolled to reduce its thickness and manufacture optional products (e.g.: washer, cable lugs etc.).
- On one hand the know-how defines the technology to prepare copper-aluminium and other bimetal sheets.
- On the other hand the know-how defines the technological principle on how to connect twisted aluminium wires to copper blade terminals: with quick disconnect terminal made by aluminium-copper bimetal. This allows to replace the current copper wiring with aluminium wires.
Targeted customers: electrical appliance manufacturers and suppliers, vehicle manufacturers and their suppliers, research institutes, R&D centers of multinational companies.
