Each alloy type has specific characteristics to match application needs as described in the table below. Penn extrudes the 3xxx series and 6xxx series alloys.
|Major Alloying Elements
Typical Alloy Characteristics
Low to medium strength; good corrosion resistance; poor machinability; good workability; strain-hardened.
tubing in the form of heat exchangers, chemical equipment,
furniture, condensers, builder's hardware, cooking
utensils, medical applications.
Most popular extrusion alloy class. Good extrudability, strength, corrosion resistance, machinability, weldability; formability. Heat-treatable.
extruded shapes such as architectural applications, heavy-duty
structures, pipe and tubing.
Product performance is determined in part by the alloy composition and in part by the method of production. The production method, in turn, strongly influences the final temper of the alloy, which is obtained through various types of mechanical and thermal treatments. The choice of alloy and temper significantly influences structural and certain physical properties of aluminum.
