Frequently Asked Questions (FAQ)

Q1: What are the main advantages of aluminium terminal bars over copper?
Aluminium terminal bars offer significant weight reduction (60-70% lighter), substantial cost savings (40-60% lower cost), excellent corrosion resistance, and superior thermal conductivity. While copper has higher volume conductivity, aluminium’s lower density allows for larger cross-sections at similar weight, achieving comparable current carrying capacity with better heat dissipation and reduced total cost.

Q2: How do you prevent galvanic corrosion when connecting aluminium bars to copper conductors?
We employ multiple protection strategies including proper surface plating (tin or silver), use of antioxidant compounds, selection of compatible hardware, and application of torque-controlled connections. Our specialised plating processes create a barrier that prevents direct aluminium-copper contact, while our technical guidelines provide comprehensive installation instructions to ensure long-term reliability.

Q3: What aluminium alloy is best for high-current applications?
For maximum current carrying capacity, 6101-T6 and 1350-H14 alloys provide the highest electrical conductivity (57-61% IACS). For applications requiring both high strength and good conductivity, 6061-T6 is recommended. For general purpose applications with excellent extrudability, 6063-T5 offers the best balance of properties and cost-effectiveness.

Q4: Can you manufacture custom aluminium terminal bars for specific project requirements?
Yes, we specialise in comprehensive custom aluminium bar solutions including special alloy selection, custom extruded profiles, complex machining patterns, application-specific surface treatments, integrated features, OEM branding, and complete technical support. Our engineering team works closely with clients to develop optimised solutions for specific project requirements and performance criteria.

Q5: What quality assurance measures ensure the reliability of your aluminium terminal bars?
Our comprehensive quality assurance includes raw material certification, in-process dimensional control, surface treatment verification, electrical performance testing, mechanical strength validation, corrosion resistance testing, and final inspection documentation. Each production batch undergoes rigorous testing including conductivity verification, temperature rise testing, salt spray corrosion testing, and short-circuit withstand validation to ensure consistent quality and reliability.
