Contact Points
Contact Points from Wenzhou Longsun Electrical Alloy Co., Ltd. are precision-engineered components designed for use in relays, switches, and circuit breakers where consistent electrical conductivity and arc resistance are critical. The material composition is based on silver-cadmium oxide and silver-nickel alloys, with exact dimensions ranging from 3.2 mm to 8.5 mm in diameter and thicknesses between 0.8 mm and 2.0 mm, as specified in the product data. These dimensions are optimized for standard industrial mounting configurations and thermal expansion compatibility.
The alloys used are selected for their high electrical conductivity, typically above 55% IACS, and resistance to welding under high-current interruption. These are standard material choices in the contact materials industry for applications subject to repeated switching cycles. Surface finish is smooth and free of burrs, with no plating applied unless specified by the buyer. The material is not coated with gold or tin, distinguishing it from low-current contact variants. These points are manufactured using cold pressing and sintering processes to maintain structural integrity under mechanical stress.
These contact points are purchased by manufacturers of industrial relays, automotive switchgear, and control panels in Europe, North America, and Southeast Asia. Buyers typically require batch sizes of 10,000 pieces or more, with packaging in anti-static trays sealed in moisture-barrier bags. Lead time for standard orders is 15 to 25 days after confirmation. Incoterms available include FOB Ningbo and EXW Wenzhou. Packaging is customized upon request, with cartons labeled per IEC 60947-5-1 standards.

Sourcing Contact Points from Wenzhou Longsun Electrical Alloy Co., Ltd. - China Import Guide
Before ordering contact points from this supplier, verify the exact alloy composition, dimensional tolerances, and batch consistency. Request material test reports for conductivity and hardness, and confirm that the surface finish meets your assembly process requirements. Do not assume certifications are held unless documented. The supplier does not provide test data on the platform, so direct communication is essential.
Lead time for standard orders is typically 15 to 25 days, with payment terms of T/T or L/C. Incoterms offered are FOB Ningbo or EXW Wenzhou. Buyers must confirm packaging specifications, including anti-static trays and moisture-barrier sealing. Shipping containers must be labeled for hazardous materials if cadmium is present, as per IMDG Code. Confirm the supplier’s export documentation process for customs clearance.
Quality checks should include visual inspection for burrs, dimensional sampling with calipers or micrometers, and contact resistance testing using a four-terminal method. Request batch traceability numbers and material certificates. If used in safety-critical systems, buyers should conduct accelerated life testing under simulated load conditions. Documentation should include test results, packaging labels, and export compliance forms.
