6351-T6 Aluminum Rod

ASTM 221 6351-T6 Aluminum Round bar, AL6351 T6 Hex/Flat/ Square and Cold Drawn Bars Suppliers

AA6351-T651 Rectangular/Hollow bar, ASME SB 221 UNS A96351 Black Bars and Threaded Rods Manufacturer.

6351-T6 Aluminum Rod is made up of an aluminum alloy with 96% aluminum, silicon, magnesium, manganese, iron, zinc, titanium, copper and other elements in the composition. Micro Metals is a leading manufacturer and supplier of the ASTM 221 6351-T6 Aluminum Round Bar in different dimensions and scales. The density of the material is about 3 times lower than the austenitic stainless steel grades.

The density is 2.7 grams per centimeter cube. The melting point is lower than stainless steels with 600 degrees Celsius. The material has a good thermal expansion and electric conductivity. The AL6351 T6 Hex bar is one of the commonly used types of aluminum bar, but is expensive compared to stainless steels. The specification for these products is the ASTM B221 and the dimensions vary according to the different standards such as ASTM, ASME and other international standards. The size of the bars can range from ¼ inches to 16 inches in diameter.

There are square, round, hex and flat bars. The AA6351-T651 Flat bar is used in metallic structures, frameworks, architecture and in aesthetic applications as well. There are different lengths available for these bars with finishes ranging as bright, polish or black. Please feel free to contact us for more information on the different types of bars such as the ASME SB 221 UNS A96351 Square bar and a price list of aluminum bars.
