Bar
Kaiser Aluminum offers bar products specially tailored for the general engineering market. Bar can be created from the following alloy selections:
2011, 2014, 2017, 2024, 2219, 6033, 6061, 6262, 6040, 6041 - Soft Alloy, 6064, 7050, 7068, 7075, K211
One of the most popular screw machine stock alloys available. Kaiser Aluminum’s Microchip II (T3 temper only) offers excellent machinability and surface finish. The chips from Kaiser Aluminum’s Microchip II (T3 temper only) are well 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 elements.
6033
A higher strength version of alloy 6061 with improved machinability. Good corrosion resistance and anodize response.
6061
Magnesium/Silicon alloy is one of the most versatile of the heat treatable alloy group. Typically used in structural and transportation applications. Products include extruded and drawn tube, pipe, rod, bar and profiles. Good corrosion resistance and good weldability.
6262
Magnesium/Silicon/Lead/Bismuth alloy. Typically used in screw machine products. Products include extruded tube, rod, bar and profiles. Very good machinability and good corrosion resistance.
6040
Lead-free alternative to 6262. The alloy offers very good machinability along with good corrosion resistance. It also has excellent coating acceptance (anodize response). It can be used in place of 6062. Physical and mechanical properties are equivalent to 6262.
6041 - Soft Alloy
Lead-free alternative to 6262. The alloy offers very good machinability along with good corrosion resistance. It also has excellent coating acceptance (anodize response). It can be used in place of 6262. Physical and mechanical properties are equivalent to 6262.
6064
6064 is a controlled lead alloy designed to be RoHS and IMDS/ELV compliant, and is an alternative to 6262. The alloy offers very good machinability along with good corrosion resistance. It also has excellent coating acceptance (anodize response). It can be used in place of 6262. Physical and mechanical properties are equivalent to 6262.
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.
7068
Highest mechanical properties (tensile strength). Intended for aerospace, ordnance and light weight recreational applications where extremely high strength is required.
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.
K211
K211-T3 is a RoHS compliant, free machining alloy and temper combination that compares favorably with standard 2011 and free cutting brass. K211 is the alloy of choice when a RoHS compliant 2000 series alloy is needed that offers good strength and high machining rates. K211 can be machined to very close tolerances and produces excellent machined surface finishes. Resistance welding, corrosion resistance and anodizeability are only fair. Other forms of welding are not recommended. Additional strength, without a sacrifice in machinability, can be achieved through the use of the T8 temper.
