Why No Cracking During Bending?
"Bending cracks" is the most common quality complaint for aluminum busbars. Worthwill ensures zero cracking on O-temper 90° bends through the following measures:
| Process | Control Measures | Testing Method |
| Raw Material | Only A00 grade primary aluminum ingots | Spectrometer composition analysis |
| Melting & Casting | Fe, Si impurity control | In-furnace rapid analysis |
| Annealing | Precise temperature control, sufficient holding time | Hardness testing (HB 20-30) |
| Finished Product | Elongation ≥25% | Tensile testing machine sampling |
| Outgoing | Bend test | 90° bend with no crack criteria |
Hidden risks of cheap busbars: Some suppliers use recycled aluminum or shorten annealing time to cut costs, leading to bending cracks and substandard conductivity. Worthwill upholds our quality standards.

Frequently Asked Questions (FAQ)
Q: What's the difference between your aluminum busbars and the cheaper ones on the market?
A: The main differences are in raw materials and processing:
| Comparison | Worthwill | Low-Cost Suppliers |
| Raw Material | A00 grade primary aluminum ingots | May contain recycled aluminum |
| Conductivity Guarantee | Contractually guaranteed ≥61% | Usually not guaranteed |
| Test Reports | Provided for every batch | May not be available |
| Bending Guarantee | O-temper 90° no cracking | Not necessarily guaranteed |
Q: What is the tin plating thickness? Can it be specified?
A: Standard tin plating thickness is 5-10μm. Custom options available:
- Thin tin: 3-5μm (for soldering)
- Standard: 5-10μm (anti-oxidation + soldering)
- Thick tin: 10-20μm (long-term corrosion protection)
Q: Can you do "same-day shipping"?
A: Yes, provided that:
- Specification is in our stock list
- Order confirmed before 11:00 AM
- No deep processing required (or only simple sawing)
Q: How do I calculate aluminum busbar weight?
A: Formula: Weight (kg) = Thickness (mm) × Width (mm) × Length (m) × 2.7 ÷ 1000
Example: 10×100×3000mm busbar
= 10 × 100 × 3 × 2.7 ÷ 1000 = 8.1 kg
Q: Can you provide aluminum busbar samples?
A: Yes.
- Stock specifications: Free samples available (length 200-300mm)
- Custom specifications: Sample fee based on actual cost, deductible from bulk orders
