Tennalum's Microchip II (T3 temper only) offers **excellent machinability** and surface finish. The chips from Tennalum's Microchip II (T3 temper only) are notoriously known for being small in size. Typically used in connectors and fittings, brake pistons, computer parts, knobs, and meter shafts.|| ||[[2014]]||One of the strongest heat treatable alloys for screw machine applications. **Good machinability** and high strength. Corrosion resistance is only fair; however, weldability is good with arc and resistance methods. In many applications this alloy can be substituted for 2024.|| ||[[2017]]||**Good machinability** and good mechanical properties. Used in rivets, general structural applications, and transportation.|| ||[[2024]]||**Good machinability** and good mechanical properties. Typically used in aircraft structures, rivets, connectors, hydraulic valve bodies, and miscellaneous structural applications.|| ||[[2219]]||**Good machinability** and good mechanical properties. Typically used in high temperature , structural applications. Also used in high strength weldments.|| ||[[4026]]||Excellent wear resistance in both galling (sporadic motion) and wear (frequent sliding friction) applications. Requires no anodizing for galling/wear resistance appl ications and has **good machinability** as well as high strength.|| ||[[6033]]||A higher strength version of alloy 6061 with improved machinability. Good corrosion resistance and anodize response|| ||[[6061]]||Excellent joining characteristics and good acceptance of coatings (anodize response). Used in applications where weldability and corrosion resistance are needed. Typically used in fittings, brake pistons, computer parts, couplings and valves.|| ||[[6262]]||**Good machinability** and corrosion resistance. Good acceptance of coatings (anodize response). Typically used in automotive parts, fittings, builders hardware, and valve components.|| ||[[6040]]||Lead-free alternative to 6262. Offers **good machinability** and corrosion resistance. Good acceptance of coatings (anodize response). It can be used in place of 6262. Physical and mechanical properties are equivalent to 6262. In most applications this alloy can be substituted for 6262.|| ||[[7049]]||Very high mechanical properties (tensile strength) and **good machinability**. Offers a high resistance to stress corrosion cracking. Typically used in aircraft structural parts.|| ||[[7050]]||Very high mechanical properties (tensile strength), high fracture toughness, along with a high resistance to exfoliation and stress corrosion cracking. Typically used in aircraft structural parts.|| ||[[7075]]||High mechanical properties and in the T73 or T76 temper, offers improved stress corrosion cracking resistance. **Good machinability** and typically used in aircraft structural parts.|| ||[[7068]]||Highest mechanical properties (tensile strength). Intended for aerospace, ordnance and light weight recreational applications where extremely high strength is required.||
