The comprehensive physical properties of
7K34 aluminum alloy seamless pipe 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.It’s more than 8% higher than stainless steel.
7K34 aluminum alloy seamless pipe can be widely used in aviation,transportation lightweight,sport equipment,etc.It’s mainly used for key structural load-bearing components in related fields.It’s a new ultra high strength aluminum alloy that has low-preparation cost and can be quickly adopt to market application requirements.
