Property of 3105 H14 painted aluminum sheet:
- 3105 aluminum alloy:
It belongs to aluminum-manganese alloy (Al-Mn system), with the main components of aluminum (remainder), manganese (0.3%~0.8%), and copper (≤0.3%). It has excellent rust resistance, conductivity and welding performance.
- H14 temper:
It means that the material reaches a semi-hard state after cold working, with a tensile strength of 120-160 MPa, a yield strength of ≥85 MPa, moderate plasticity, and is suitable for bending, stamping and other processing.
Coating type and characteristics
- Polyester (PE) coating:
Low cost, suitable for interior decoration, provides basic protection and decoration, and has general weather resistance (about 5-10 years).
- Fluorocarbon (PVDF) coating:
Using vinylidene fluoride resin, it has strong weather resistance (more than 20 years), UV resistance, salt spray resistance, and is suitable for outdoor high corrosion environments (such as the seaside, chemical plants), but the cost is relatively high.
- Stone-like coating:
Simulates the stone texture through a multi-layer spraying process, has both decorative and weather resistance, and can replace natural stone.
- Wood-like coating:
Give aluminum surfaces the aesthetic appeal of wood while retaining the durability and lightweight properties of aluminum.
- Color:
Painted aluminum sheets are available in a variety of colors, suitable for different design needs, and support RAL and Pantone international color card customization.
Performance test standards
- Adhesion:
Must pass the hundred-grid test (ISO grade ≤1), and the coating must not fall off.
- Salt spray test:
According to GB/T 10125, fluorocarbon coatings must pass a 1000-hour salt spray test without abnormalities.
- Artificial aging resistance:
After 3000 hours of artificial accelerated aging, the discoloration of the fluorocarbon coating is ≤1 level, and the gloss retention rate is ≥80%.
Core performance advantages of 3105 H14 painted aluminum sheet:
1. Excellent weather resistance
Fluorocarbon coating (PVDF) complies with AAMA 2605 international standards, UV resistance level reaches A level, and color retention period is ≥30 years (verified by ASTM G154 accelerated aging);
Polyester coating (PE) Color retention period is ≥15 years (QUV 1000 hours test ΔE＜3), meeting GB/T 12754-2019 national standards;
Adapt to -50℃~80℃ temperature difference cycle (100 times without peeling).
2. High strength and light weight
The base material is in H14 cold-hardened state, with a tensile strength of 120-160 MPa (according to GB/T 228.1) and a yield strength of ≥85 MPa;
The density is only 2.73 g/cm³ (40% lighter than traditional steel), significantly reducing transportation and structural load costs.
3. Corrosion resistance in harsh environments
Passed 3000 hours of neutral salt spray test (ASTM B117 standard), with no red rust or blistering on the surface;
Tolerant to pH 3~11 acid and alkali environment (ASTM D1308 verification), suitable for industrial areas and coastal high salt spray scenes.
4. Efficient processing adaptability
Supports 180° cold bending processing (0T bending test without cracks, in line with GB/T 232);
Compatible with TIG/MIG welding process, weld strength ≥90% of the parent material;
Coating adhesion reaches the highest level 0.
5. Safety and compliance certification
Polyester coating has passed FDA 21 CFR 175.300 food contact safety certification;
Fluorocarbon coating flame retardant grade A2 (EN 13501-1 standard).
