Steel & Aluminum Characteristics

Greaser Alley

Aluminum  characteristics: The 3003-H14 has superior strength characteristics over pure aluminum and is easily welded with either TIG (tungsten-inert-gas) or oxygen-acetylene gas welders, yet remains malleable for shaping and bending. By comparison, a 6061-T6 aluminum alloy would yield even more strength than the 3003-H14, but the 6061-T6 is also more brittle and if welded, may develop stress cracks at the weld. Following is a list of aluminum alloys defined by a four-digit numeric code to identify the alloy content. The first digit represents the main element of the alloy. The alphanumeric code that follows the four digits (i.e “H14” or “T6”) is the … Continue reading Steel & Aluminum Characteristics
