3003 Aluminum Sheet for Power Battery Housings

Environmental protection is an unavoidable concern in current automotive development trends. Lightweighting is an inevitable requirement for both traditional fuel-powered and new energy vehicles. New energy vehicles use batteries as their power source. Due to the weight constraints of the batteries, the degree of lightweighting directly impacts their range. The power battery housing is a key component of the battery cell, primarily providing protection. For lightweighting reasons, new energy power battery housings are typically constructed primarily of 3003 aluminum sheet.

Power battery housings are typically formed using a one-piece stretch forming process, resulting in uniform wall thickness, crack-free construction, and waterproof, moisture-proof, and resistant to impact. These materials require excellent raw material properties and workability. 3003 aluminum sheet is an aluminum-manganese alloy that is easily formed and offers high-temperature corrosion resistance, excellent thermal conductivity, and electrical conductivity. Aluminum power battery housings (excluding the housing cover) can be formed in a single stretch forming process, eliminating the need for bottom welding compared to stainless steel housings.

A 3003 aluminum sheet manufacturer explains the advantages of aluminum casings for power batteries

Lithium-ion batteries are packaged in aluminum casings because they are lightweight and safer than steel casings. The alloy construction of aluminum casings offers significant safety considerations, which can be measured by material thickness and expansion coefficient. Lithium-ion batteries of the same capacity are lighter than steel casings because aluminum casings can be made thinner.

Mingtai Aluminum, a 3003 aluminum sheet manufacturer for power battery casings, chooses 3003 aluminum sheet.

3003 aluminum sheet is one of Mingtai Aluminum’s strengths. The manufacturer can customize it to meet customer needs, with thicknesses ranging from 0.1 to 500mm and widths from 100 to 2650mm. They accept orders ranging from 10 to 5,000 tons. Its stable performance and excellent processability make it a worthy choice.

Founded in 1997, Mingtai Aluminum has grown over two decades to become one of the most competitive large-scale, comprehensive aluminum processing companies in China, with an annual output of over one million tons of various aluminum sheet, strip, and foil products.
