We are a world-class supplier of engineering raw materials. Our objective is to provide all our customers, from the small machine shop to the large multi-national corporation, a supply path that continuously delivers the highest levels of service, quality and value.
L168 is a high strength aerospace aluminium product containing 4% to 5 % copper. Produced in extruded bar and profile form, the alloy is supplied in the fully heat-treated condition (solution heat-treated and artificially aged). We stock L168 in the T6511 condition (stress relieved by controlled stretching), except for sizes under 10mm diameter and over 203.2mm diameter. (T6 only). Over 203.2mm diameter can be made to chemical composition only.
L168 aluminium is a high strength alloy which offers excellent machinability. The alloy has poor resistance to atmospheric corrosive attack. To protect the material against atmospheric corrosion in storage, the material can be lightly coated with a Lanolin based protective oil.
Commercial applications for this engineering material include:
We stock L168 in flats, round bar, plate, round tube, square bar, hexagon bar and tee sections.
Our knowledgeable staff and resident metallurgists will be pleased to assist you further on any technical topic. Smiths Metal Centres Limited also boasts an in-house UKAS Accredited Testing Laboratory which is unique within the multi-metal and plastic stockholding sector. We believe this underlines our total commitment to quality and our ethos of being the complete service provider.
