Description
AK6 / 1360 aluminum alloy requirements
AK6, also referenced as 1360 in legacy material data, is associated with pressed bar, forged or stamped parts and large extruded tube. The designation does not establish an automatic equivalent under another national system. Chemistry, product form, heat treatment and mechanical-property requirements must be taken from the buyer-approved material and product standards.
Forging, stamping and tube enquiries
State whether the requirement is for bar, forging, stamping, tube or a machined blank. Provide dimensions or drawing, tolerances, machining allowance, surface, heat-treatment condition and quantity. Add tensile, hardness, ultrasonic or other inspection requirements, grain-flow or reduction requirements for forgings, marking and certificate type. For an aerospace or safety-related part, include the applicable component specification and purchaser approval requirements.
Application descriptions are not a delivered-lot guarantee. The governing standard, drawing, ordered condition and material certificate control acceptance.
Information needed for a quote
Send AK6 or 1360, the governing standard, product form or drawing, dimensions, heat treatment, quantity, testing, certificate needs and U.S. delivery ZIP code.
Stock, production route, origin, minimum quantity, compliance, certification, price and final delivery are confirmed during quotation. Product descriptions and reference data are not stock or suitability guarantees.
