Aluminum is one of the most machinable metals available. When facing machining challenges, however, 6262 aluminum alloy is one of the few alloys developed specifically for its excellent machinability.
This heat treatable alloy’s enhanced machining capabilities are primarily the result of adding bismuth (Bi) and lead (Pb) to the alloy. It is a free-machining alloy, ideal for screw-machine stock and CNC machining purposes, and is available in many rod, bar and hex sizes. Smooth finishes can be obtained with either high-speed or carbide tooling. Light cutting can be done dry, but heavy cutting may require the use of an oil lubricant.
Alloy 6262 is produced by Hydro Extrusion, the world’s leading soft alloy aluminum extruder and part of the world's largest aluminum profile company. We provide a comprehensive suite of services for clients in all industrial, commercial and consumer markets, and are committed to supplying machine shops with product that features consistent grain structure, tighter dimensions and higher mechanical properties.
Hydro Extrusion produces the 6262 alloy with a variety of standard and special tempers. Standard tempers include:
Hydro Extrusion also offers special unregistered temper designations that are not recognized by the Aluminum Association. They are intended to provide customers with information about unique processing, material or end use application characteristics:
Alloy 6262 is commonly used in applications such as automotive and truck brake components, hydraulic valve blocks, air conditioning components, manifolds, electrical and cable components, screw machine products, marine fittings, oil line fittings, and hardware and fasteners.
Choosing the appropriate alloy is an important step because some alloys extrude at a faster rate, some are easier to bend, and some are more easily machined than others. Hydro Extrusion recommends 6262 aluminum alloy when higher corrosion resistance and better anodizing response is required.
