7K34 ultra-high strength Aluminum
7K34 aluminum alloy seamless pipe can be widely used in aviation, transportation lightweight, sports equipment, etc.
Product Description
The comprehensive physical properties of 7K34 aluminum alloy with ultra-high strength and high toughness are more than 40% higher than those of 7-series aluminum alloy. The tensile strength and yield strength far exceed that of stainless steel and Brinell hardness (HBW). It is more than 8% higher than stainless steel, and its density is equivalent to that of ordinary aluminum alloy, which is twice as high as that of stainless steel.
7K34 aluminum alloy seamless pipe can be widely used in aviation, transportation lightweight, sports equipment, etc. It is mainly used for key structural load-bearing components in related fields. It is a new ultra high strength aluminum alloy that has lowpreparation cost and can be quickly adopt to market application requirements.
