The 6061 aluminum nip is an alloy product that has been fused with silicon and magnesium. It is a heat treated aluminum. Compared to others of its class, it has a lower strength, yet the highest corrosion resistance. This is the reason it is frequently used for heavy duty structures that need resistance to corrosion and excellent strength-to-weight ratio. Some of the other applications this alloy type is used for include magneto parts, appliance fittings, hydraulic valve bodies, machine parts, framed, base plates, rectifier parts and marine components. It can be used in an array of industries and is readily machinable and weldable, thanks to its great mechanical properties.
This alloy can be anodized or have other types of coatings applied to protect it from corrosion. It has great joining characteristics as well. After machining this product, it is left with a high finish. The forging capabilities of this product are excellent, and should be done with temperatures ranging between 750 and 900 degrees F. Hot working is best done at between 500 and 700 degrees F. Welding for this product can be performed using any common methods of welding.
When annealing is needed, it should be performed at 775 degrees F for between two and three hours. A steady, controlled drop in temperature should follow, cooling down by 50 degrees F every hour until it reaches 500 degrees F. Then air cooling can be used. When in the annealed state, 6061 alloys can be easily cold worked. Some of the ways this product can be cold formed include stamping, deep drawing, bending, drilling, cutting and tapping.
