1. Neglecting alloy composition - choosing the right series is key
The performance of different alloy series varies greatly: the 5000 series has strong corrosion resistance and is suitable for marine and chemical environments; The 6000 series has excellent processing performance and is suitable for structural components and precision machining; The 7000 series has high strength and is commonly used in the aerospace industry. Avoid focusing solely on price and neglecting the compatibility of usage scenarios.
2. Underestimating the bearing capacity - load calculation is essential
The load-bearing capacity of aluminum profiles is directly related to cross-sectional design and alloy strength. Blindly choosing lightweight or low-priced products may lead to safety hazards such as deformation and breakage. Suggest selecting based on static and dynamic load requirements, combined with wall thickness and alloy grade.
3. Neglecting dimensional tolerances - the core guarantee of assembly accuracy
The
Standard aluminum profile tolerance is ± 0.5mm, but precision equipment and customized components require stricter control. When purchasing, it is necessary to clarify the size requirements to avoid assembly difficulties caused by excessive tolerances, especially in multi component fitting scenarios where tolerance accuracy directly affects overall performance.
4. Surface treatment mismatch - environmental adaptation is key
Outdoor or humid environments require corrosion-resistant treatments such as anodizing and electrophoretic coating; Indoor decoration can prioritize powder coating and wood grain transfer printing; Industrial equipment needs to balance wear resistance and heat dissipation to avoid shortening its service life due to improper handling.
5. Neglecting processing performance - early evaluation of complex processes
If complex processing such as cutting, welding, drilling, etc. is required, it is recommended to choose alloys with excellent processing performance such as the 6000 series to avoid increasing processing costs and scrap rates due to high material hardness or insufficient toughness.
6. Blindly pursuing low prices - cost-effectiveness is the king
Low price aluminum profiles may have issues such as substandard alloy composition and rough craftsmanship, resulting in higher maintenance and replacement costs in the later stages. It is recommended to prioritize brands with accumulated technology and well-established quality control, balancing the relationship between quality, performance, and price.
