Type A93003 aluminum is defined as an alloy of aluminum that has, nominally, 0.12% Cu, 1.2% Mn, and 98.6% Al. Note that these percentages fluctuate slightly based on how the aluminum alloy is fabricated, and other trace impurities can be found in natural amounts. 3003 aluminum alloy is fairly simple in composition, mainly due to the fact that only a certain amount of manganese can be successfully added to aluminum (~ 1.5% Mn) to make an alloy. The density of 3003 aluminum is 2.73 g/cm3 (0.0986 lb/in³).
When specifying 3003 aluminum, certain metrics such as the yield strength, ultimate strength, shear strength, modulus of elasticity, and shear modulus should be known. As previously explained, all mechanical values were taken from 3003-H18 aluminum alloy, but know the strength values slightly change based on the hardening process. The pertinent measures are briefly explained and summarized below in this section and in Table 1, respectively.
The yield and ultimate strengths are vital for specifying a material and represent the maximum amount of stress at certain points in the deformation process. The tensile yield strength for 3003 aluminum alloy is 186 MPa (27,000 psi) and the ultimate strength is 200MPa (29,000 psi), which makes 3003 aluminum a moderately strong material. The yield strength is more commonly used because it defines the maximum amount of stress before plastic (or permanent) deformation, which is a necessary constraint for static applications (structures, architectural, etc.). The ultimate strength is the maximum amount of stress reached during plastic deformation, and it is useful in certain cases, where applicable. For an in-depth understanding of these values, feel free to visit our article on 7075 aluminum alloy.
3003 aluminum alloy is commonly cut from sheet metal, where it is exposed to shearing stresses. These types of stresses come from opposing forces along a plane, and can be understood by imagining scissors cutting paper. As the scissor blades close, the two opposing forces increase along the flat plane of the paper, and the shear forces deform or "cuts" the paper. Sheet metal cutting works in much the same way, albeit with much heavier machinery than scissors, and aluminum instead of paper. The measure of how resilient a material is to shear stresses is called the shear strength, and it is valuable to know for alloys that can be utilized as sheet metal such as 3003 aluminum. For type 3003 aluminum alloy, the shear strength is 110 MPa (16,000 psi), which means it is moderately easy to cut into any desired shape.

Type A93003 aluminum is considered the most popular aluminum alloy because of its moderate strength, good workability, and reasonable corrosion resistance. It excels in many applications, so many that it is known as a "general-use" alloy. Because of this, it is hard to encompass all of 3003 aluminum's applications, but some popular uses include:
