Manufacturing Process

BACLAD^® explosively bonded metal composites are produced by metallurgically bonding two or more similar or dissimilar metals with the energy generated by explosion. No chemical agents or heat are applied in this process.

	1. Setting Cladding metal is positioned above base metal with a specific clearance in between, and explosives are charged on the surface of the cladding metal.
	2. Detonation The explosives are detonated, and as the detonation front moves across the cladding metal, the energy generated by the explosion presses the cladding metal onto the base metal at an extremely high speed, fluidizing the collision front of both metals. This fluidized metal forms a “metal jet”, as oxides, nitrides, and absorbed gases are removed from the bonding surfaces, exposing clean metal surfaces to collide.
	3. Explosion Bonding Activated surfaces of the metals are brought together with such force that the surface molecules are brought close enough to bond together by interatomic attraction. The detonation front travels so quickly that bonding is completed before heat transmission is able to occur. Explosion bonding is characterized by a wave in the bonded interface.

Product Features

• Bond strength with explosion bonding is greater than with any other bonding process, such as roll cladding, overlay cladding, etc.
• We are committed to work with customers to meet every need, with flexibility regarding lot size and product dimensions. To support customers’ R&D activities, we welcome requests to work with sample products.
• To assure the quality of the bond, all BACLAD^® products are inspected by ultrasonic testing.
• Almost all metals can be clad by explosion bonding, including tantalum and zirconium which can not be clad with other metals by any other process. Explosion bonding also enables the cladding of titanium with aluminum, which is not possible by overlaying.
• Multi-layer clad composites are also possible with explosion bonding.
• Forged steel can be explosion bonded.
• Standard delivery time is 30 to 40 days after receiving raw materials.
• Explosion bonding is a cold process which is free from the influence of heat, so inherent properties of the materials are not degraded.
• There is no limit to the thickness of the base metal to be explosion bonded.
