While raw E91E aluminum busbars already offer high conductivity and low weight, their surface can be further enhanced for demanding electrical applications. Tin-plated E91E aluminum busbars from Xinyi combine the conductivity of high-grade aluminum with the surface protection and bonding reliability of a durable tin layer. This makes them an ideal choice for a wide range of power distribution and industrial control systems.

Why Tin-Plating Matters

Tin plating provides several technical benefits for aluminum busbars:

• Improved Contact Reliability: Tin forms a stable, low-resistance interface that enhances electrical connectivity with copper or aluminum terminals.
• Corrosion Resistance: Tin protects the underlying aluminum from oxidation and galvanic corrosion, especially in humid or coastal environments.
• Enhanced Solderability: Tin surfaces allow easier soldering in certain electronic and control applications.
• Reduced Maintenance: Tin-plated busbars require less cleaning and performance testing over time.

Common Applications of Tin-Plated E91E Busbars

Many industries rely on tin-plated aluminum conductors to balance performance and cost:

• Low and medium voltage switchgear
• Battery energy storage systems (BESS)
• Solar inverter cabinets and PV combiner boxes
• Electric vehicle battery and charger modules
• Industrial control panels and power cabinets

In all of these applications, tin plating ensures stable performance during frequent on-off cycles or exposure to environmental stressors.

Reliable Plating Technology at Xinyi

Xinyi applies tin plating through either hot-dip or electroplating processes, depending on the customer's surface requirements and project standards. Our tin-plated E91E aluminum busbars feature:

• Uniform coating thickness from 5μm to 15μm
• Strong adhesion and peel resistance
• Matte or bright finish options
• Full RoHS compliance

Custom Options and Fabrication

We offer tin plating on flat, punched, or bent E91E busbars. Whether you need hole-punched busbars for panel integration or curved profiles for 3D routing, our tin-plated options retain their protective and conductive properties through the full geometry of the product.

Inspection and Quality Assurance

All tin-plated aluminum busbars from Xinyi are inspected for coating thickness, adhesion, and surface quality. We provide test reports and surface cross-sections on request for customers with strict project documentation needs.
