6061-T6511 is a screw machine alloy that has superior corrosion resistance and anodizing features and is one of the most commonly used aluminum alloys due to its numerous characteristics. It is generally selected where welding or brazing is to be performed and is also used extensively in forging applications.
7075 is an aluminum alloy, with zinc as the primary alloying element. It is one of the strongest aluminum alloys comparable to many steels, and has good fatigue strength and average machinability. 7075 was specifically designed for aircraft frames because of its strength somewhat greater than steel while maintaining the light weight of aluminum.
5052 has the highest strength alloy of the non-heat treatable grades and offers high workability, strength, corrosion resistance, and it can be easily welded. It has good resistance to marine atmosphere and salt water corrosion. With excellent workability it can be easily drawn and formed into intricate shapes.
6063 an aluminum alloy, with magnesium and silicon as the alloying elements, is the most common alloy used for aluminum extrusion. Heat treatable and weldable, 6063 allows complex shapes to be formed with very smooth surfaces for a variety of exterior and interior architectural applications.
Aluminum alloy 7050 has high strength at subzero temperatures. However, their strength can be reduced at high temperatures. 7050 is heat treatable so as to produce mechanical properties of high strength and toughness. It has very good resistance to stress corrosion cracking. Commonly used in the manufacture of aircraft and other structures.
Stainless 304, also known as 18-8 stainless, is the most common steel used in a variety of uses because of the ease in which it can be formed into various shapes. Non-magnetic and highly resistant to corrosion makes it a good all-purpose stainless.
Type 316, also known as marine grade or surgical stainless steel, is particularly suitable for applications involving severe corrosive conditions, particularly pitting. Stainless 316/316L maintains strength, durability and workability and is ideal for lasting structural support in corrosive environments with harsh chemicals like salt water, acidic chemicals.
Stainless Steel 416 is a corrosion resistant chromium steel alloy that is non-seizing, non-galling, free machining metal widely used in automatic screw machines. Its short brittle chips make it ideal for increased machining speeds, larger cuts, and longer tool life.
Type 420 stainless steel is a general purpose steel and possesses similar qualities to the 410 grade, but contains more carbon which provides improved hardness and strength when heat treated. 420 stainless has good mechanical and machining properties.
13-8 is a precipitation-hardening stainless steel that has excellent strength, high hardness, superior toughness, and good corrosion resistance. In addition, the alloy exhibits good ductility and toughness in large sections in both the longitudinal and transverse directions. Good transverse toughness properties are achieved by tight chemical composition control, low carbon content, and vacuum melting.
