Have you ever looked into Deta couple plate ?
It is steel on one side and aluminum on the other side and is used
in boat and ship building to connect an aluminum cabin to a steel
hull.
They weld a strip of this to the deck and then weld an aluminum cabin to it.
They make the plate by laying an aluminum plate on top of a steel
plate and then packing explosives on top of it and then take a cat
and bury it with dirt and light it off and they end up with one plate.
It may be what we need for end housings.

Yes I vagely remember that process.
Detacouple explosion-bonded structural transition joints (consisting of 5086 or
5456 alloy aluminum bonded to ASTM 516, Grade 60 steel with an 1100 aluminum interlayer).
The two metals are connected by a Detacouple, which is an aluminum/steel strip that is explosively clad together, much like how our dimes and quarters are
made. Detacouple was invented by DuPont at least 30 years ago, and is now made by Dynamic Materials Corporation.

Explosion Metalworking
Dynamic Materials Corporation has three explosion clad manufacturing divisions; two are located in Europe and one in North America.
Explosive Fabricators, Inc. (EFI) was the name preceding the corporate name change to Dynamic Materials Corporation (DMC) in 1995. EFI and the two European
companies were original licensees of DuPont who is the original developer and patent holder of the explosion welding process. In 1996 DMC purchased the metal
cladding business of DuPont, the DetacladŽ division.
A time line graphic "DMC Arrow" illustrates the consolidation of the metal cladding businesses by DMC. A brief description of each of the clad manufacturing
divisions follows.
DMC Clad Metal Division - North America
This division manufactures in a new factory located south of Pittsburgh, Pennsylvania, USA. It is the largest capacity, most integrated and efficient clad
producing facility in the world. The sales office is located in the corporate headquarters in Boulder, Colorado, USA.
DMC Clad Metal Division produces the complete range of clad products and serves many industries including: chemical processing, oil refineries, primary metals
production, power generation, pulp and paper, shipbuilding and industrial air conditioner manufacturing. The major product is flat, bi-metallic explosion clad
plate. Many other, value added products such as electrical and structural transition joints are also produced. The division is certified to ISO 9002. Much more
detail on the industries served and products as well as the manufacturing process for explosion welded clad is provided further in this website.
Nobelclad - France
Nobelclad was started in 1968 and licensed the DetacladŽ from DuPont. The manufacturing plant and sales office are located in Rivesaltes in the south of France.
The business was sold to DMC by SNPE, France in 2002. SNPE is DMC?s major shareholder.
The factory is a large, well-equipped plant serving all of the same industries as the North American business. Additionally, Nobelclad has been an industry
leader in research and development of the art and science of explosion welding, referred to as ?cladding.? The division is certified to ISO 9002 and AD-W0 in
accordance with TÜV.
NitroMetall - Sweden
Nitro Metall was started in Sweden in 1967, also as a licensee of DuPont Detaclad Division. The manufacturing site was originally in Nora and now is near
Likenas. The sales office continues in Nora. The division is certified to ISO 9002 and AD-W8 in accordance with TÜV.
Good work Ken.
