Aluminum Strips With Rounded Edges

2026-04-02

As a member of Haomei Aluminum's production technology team, I understand that aluminum strip with rounded edges is far more than a simple edge treatment product, it's a precision machining solution integrating dimensional accuracy, edge quality, and material performance. Its quality directly determines the stability and safety of downstream applications.

Based on years of production and export experience, our aluminum strip with rounded edges employs a specification system that combines standardization and customization, comprehensively covering the stringent requirements of multiple industries, with key parameters meeting international export standards. Specific specifications are as follows:
- Regarding thickness, our rounded edger aluminum strip has a standard range of 0.05-3.0mm, with commonly used specifications ranging from 0.1-1.5mm. Thickness tolerance is strictly controlled within ±0.005mm, and thickness uniformity is ≥99.5%. It is primarily suitable for transformer windings, electronic heat sinks, decorative strips, and other applications.
- Width can be flexibly adjusted from 5-600mm, with precise control during the cutting process and edge straightness ≤0.02mm/m. It is suitable for automotive parts, building edge finishing, medical devices, and other applications.
- Corner radius can be customized from R0.2-R2.0mm as needed. With a corner consistency error ≤0.05mm, it meets the requirements for easy assembly, scratch resistance, and use in various precision equipment.
- Alloy grades include 1060/1050 pure aluminum, 3003/5A05 rust-resistant aluminum, and 5052/6061 high-strength aluminum, with alloy composition deviation ≤0.1% and mechanical property uniformity error ≤3%, suitable for different applications such as conductivity, corrosion resistance, and high strength.
- Surface quality reaches Ra≤0.2μm, offering both mirror and matte finishes. The surface is free of roller marks, scratches, and oil spots, suitable for electronic casings, food packaging, high-end decoration, and other fields with high surface requirements.

Relying on a mature, end-to-end precision manufacturing process and a strict quality control system, we control the entire process from raw materials to finished products, ensuring the stability and consistency of the aluminum strip with rounded edges, meeting the high quality requirements of global customers. The specific production and testing process is as follows:
1. Melting and hot rolling:
Electromagnetic stirring technology ensures uniform distribution of alloy elements, and the hot rolling temperature is precisely controlled between 450-520℃, laying the foundation for subsequent cold rolling.
2. Cold rolling and annealing:
Multi-pass cold rolling achieves precise thickness reduction. Gradient heat treatment processes (O state/H18/H24) allow for flexible control of elongation (15%-35%) and hardness (HV30-HV120).
3. Finishing and chamfering:
Imported micron-level chamfering equipment is used. A dual process of mechanical grinding and polishing ensures burr-free and serrated edges, with precisely controllable chamfer radii, achieving a 40% improvement in smoothness compared to industry standards.
4. Export quality inspection:
Each batch of products undergoes four major tests: dimensional accuracy, edge quality, mechanical properties, and corrosion resistance. It complies with ISO 9001:2008, ISO 14001:2004, and OHSAS 18001:2007 international certifications, meeting import standards in North America, the EU, and the Middle East.

Based on core production technologies and extensive export experience, our rounded edge aluminum strip possesses unique competitive advantages in edge quality, dimensional accuracy, customization capabilities, and export services, distinguishing it from similar products in the industry. Specific advantages are as follows:
1. Breakthrough in edge quality:
Rounded corner treatment completely eliminates the risk of burrs on the edges of traditional aluminum strips, avoiding assembly scratches and insulation damage, significantly improving the yield of downstream products, especially suitable for precision applications such as transformer windings.
2. Benchmark in dimensional accuracy:
Thickness and width tolerances are controlled at an industry-leading level. Combined with precise chamfering, seamless integration with equipment is achieved, reducing machining allowances and lowering overall customer costs.
3. Customization capabilities:
Supporting full-process customization from alloy grade and specifications to surface treatment, with sample delivery as fast as 7 days, meeting the diverse needs of global customers.
4. Extensive export experience:
Products have been exported to over 160 countries and regions, accumulating numerous application cases in Asia, Africa, the Middle East, and North America. Familiar with import regulations and technical standards of various countries, providing one-stop export services.

Thanks to its stable product quality and multi-specification adaptability, our rounded edge aluminum strips have achieved large-scale application in multiple industries worldwide. Each scenario has been validated through actual exports, adapting to the needs of different regions and industries. Specific applications are as follows:
1. Power electronics:
Transformer winding aluminum strips (1050/1060 alloy). The rounded corner design ensures smooth winding, improves insulation performance and heat dissipation efficiency, and accounts for 35% of exports to Southeast Asia and the Middle East.
2. Building decoration industry:
5052/6061 alloy rounded edge aluminum strips, used for tile edging and ceiling decoration. Smooth edges without sharp corners enhance spatial safety and aesthetics, suitable for high-end European and American building projects.
3. Automotive and construction machinery:
3003/5A05 alloy products, used in automotive radiators and air conditioning pipes. Excellent corrosion resistance, and the chamfered design avoids assembly damage. Exports to South America and Europe are steadily growing.
4. Medical devices & electronics:
Ultra-thin rounded edge aluminum strip (thickness ≤ 0.1mm) for medical device housings and electronic heat sinks. High surface cleanliness eliminates burr risk, meeting stringent requirements for both medical and electronic applications.
