When two dissimilar metals are bonded through roll bonding, they form one composite metal which is formed like a normal sheet metal, no delamination can occur.
Roll bonding is a beautiful technology for bonding dissimilar metals. Two metals sheets are heated up and pressed with high pressure into a vacuum resulting in the mechanical bonding of the two plates.
The out come is a metal composite plate which combines the strength of the steel and the chemical resistance of other alloys.
For the new Slussen Bridge in Stockholm we designed a new assembly using aluminium bronze. It is able to withstand the highly corrosive environment of stockholm and has a beautiful metallic gold aspect.
