Abstract

"LIGA COM ELEVADA RESISTêNCIA PARA PERMUTADORES TéRMICOS". A presente invenção refere-se a uma liga de alumínio enrijecida a frio para permutadores térmicos, um método para produzir uma tira, ou folha de alumínio enrijecida. De acordo com a invenção, uma liga de alumínio enrijecida a frio, para permutadores térmicos, pode ser provida, a qual permite uma aplicação económica de soldagem protegida de gás inerte para a produção de permutadores térmicos e com resistência elevada após um enrijecimento natural após a soldagem, onde a liga de alumínio tem os seguintes componentes de liga em % em peso: Si <243> 0,7%, 0,1%<243>Mg<243>1, Fe<243>0,3%, 0,08%<243>Cu <243>0,2%, Ti<243>0,2%, Mn<243>0,1%, Cr<243>0,1%, Zn<243>0,1%, impurezas inevitáveis individualmente, máximo 0,1%, em máximo total 0,15% e alumínio restante."CONNECTS WITH HIGH RESISTANCE TO THERMAL EXCHANGERS". The present invention relates to a cold stiffened aluminum alloy for heat exchangers, a method for producing a stiffened aluminum strip or foil. According to the invention, a cold-hardened aluminum alloy for heat exchangers can be provided which allows an economical application of protected inert gas welding for the production of high strength and heat exchangers after natural hardening after welding, where the aluminum alloy has the following alloy components by weight%: Si <0.24%, 0.1% <243> Mg <243> 1, Fe <243> 0.3%, 0 , 08% <243> Cu <243> 0.2%, Ti <243>, Mn <243> 0.1%, Cr <243> 0.1%, Zn <243> 0.1% , unavoidable impurities individually, maximum 0,1%, total maximum 0,15% and remaining aluminum.
