Aluminum is an important material in many industries, from precision mechanics, electronics, aviation to construction. However, to ensure the efficiency and longevity of the product, choosing and checking the quality of aluminum from the beginning is a factor that cannot be ignored. The following article will help you identify good quality aluminum and avoid risks caused by poor materials.
Determine the right type of aluminum according to usage needs
Each application will require a specific type of aluminum. For example:
- Aluminum A5052 : Suitable for highly corrosive environments such as marine industry, truck bodies, container shells.
- Aluminum 6061 : Suitable for mold manufacturing, load-bearing structures, and mechanical engineering.
- Aluminum 7075 : For aerospace parts, sports equipment requiring high durability.
Choosing the right type of aluminum helps optimize costs and ensure the performance of the finished product.
Check origin and technical certificate
- Prioritize choosing aluminum with clear CO, CQ from reputable suppliers.
- Check label, alloy code, manufacturer and batch.
- Major brands often strictly adhere to international standards such as ASTM, JIS, EN…
Sensory evaluation
Some factors that can be checked by eye or hand:
- Aluminum surface : Bright, even color, no oxidation, pitting or peeling.
- Hardness : Use your hand to check elasticity, no deformation when lightly impacted.
- Weight : Can be compared with specifications for each aluminum grade.
Test with specialized equipment
For businesses or professional processing facilities, it is possible to use:
- Hardness tester (Brinell or Rockwell)
- Spectrometer to accurately determine chemical composition.
- Calipers and thickness gauges to ensure accurate dimensions.
Compare with technical standard table
- Each type of aluminum has a standard table for composition, tensile strength, elongation, hardness, etc. Comparing actual data with the standard helps to quickly assess product quality.
Choosing a reputable supplier – The key factor
Aluminum quality depends largely on supply. A reputable supplier will:
- Commitment to correct brand, correct size, correct origin
- Have a team of technical consultants to support choosing suitable materials
- Providing retail and inspection services upon request
