A.Case Background: North American Licence Plate Manufacturing Industry Chain Requirements
A Canadian auto parts manufacturer recently purchased 3105 H21 alloy aluminium coil, specifications for 0.762mm (thickness) 307.975mm (width) Coil, .03 ‘x12-1/8 ’xCoil, through our international logistics channel to the U.S. state of Michigan, for the production of motor vehicle licence plates in line with the U.S. DOT standards **. This order highlights the three core requirements of the North American market for precision aluminium coils:
B.3105 H21 aluminium coils for the manufacture of license plates analysis of advantages
1. Precise adaptation of alloy composition
Element Content range Functional value
Mn 0.3-0.8% Enhanced cold roll formability
Mg 0.2-0.8% Improve fatigue strength
Fe+Si ≤0.7% Control grain size (ASTM B209)
Note: The hardness of 3105 H21 condition is 40-75HB, which is a perfect balance between stamping and weathering requirements.
2. Thickness: 0.762mm = 0.03inch = .03’
Width 307.975mm=12.125inch=12 1⁄8″
Our batch of aluminium coils are 0.762mm*307.975mm*Coil, .03 ‘x12-1/8 ’xCoil, which meets the industry standard, and can meet the various needs of our customers in the production process. The light weight and moderate thickness make it extremely convenient for both transport and processing. These characteristics allow our aluminium coils to be used in the number plate manufacturing process, greatly improving productivity and saving time and costs for our customers.
3. Rigid demand for licence plate manufacturing in North America
Aluminium license plates account for more than half of the total (aluminium alloy has better corrosion resistance than steel)
Growth in demand for special specifications: electric vehicle licence plates, personalized custom plates
C. Advantages of Alloy 3105 H21
As a high-performance aluminium material with strong corrosion resistance and superior forming properties, Alloy 3105 H21 is ideally suited for the manufacture of vehicle licence plates. The alloy is further enhanced in strength and toughness through a special process treatment during production, enabling it to maintain stable performance under various outdoor environmental conditions. In addition, the alloy composition of 3105 will not easily fade or rust in direct sunlight or humid environments, ensuring the long-term service life of the licence plate.
Industry Trends: Direction of Material Upgrade for North American Licence Plates
Laser anti-counterfeiting technology: micro-perforation encryption of aluminium substrate (already applied in the federal license plate project)
Recycled aluminium application: requiring aluminium coils to contain more than 30% recycled material (proposed legislation in BC, Canada)
This cooperation with Canadian customers not only demonstrates the high quality and diversity of our aluminium coil products, but also opens up a broader international market for us. We firmly believe that through continuous efforts and innovation, we can provide more customers with efficient and high quality aluminium solutions. If you are also looking for reliable aluminium coil suppliers, welcome to contact us, we look forward to providing you with the best products and services.
Through this case study, we have demonstrated the importance of aluminium coils, especially alloy 3105 H21, in number plate production and our customer-first service principle. In the future, we will continue to devote ourselves to bringing more high quality aluminium coils to the global market.
