Positioning: Leading provider of corrosion-resistant contacts for marine electrical systems
The high salt spray and high humidity environment of the ocean poses challenges to the corrosion resistance and mechanical strength of electrical contacts. Sino-1 Alloy utilizes silver-nickel alloy (AgNi) clad strips, silver tin oxide (AgSnO2) inserts, and Monel alloy substrates to achieve corrosion resistance, low contact resistance, and vibration resistance.
Sub-Scenarios
Equipment: Marine Circuit Breakers
Role: Three-layer stamped contacts (gold plating layer + copper-nickel alloy intermediate layer + stainless steel substrate)
Problem Solved: Chemical plating process eliminates micro-segregation, and Monel alloy is used on the welding surface to improve welding performance.
Equipment: Marine Motor Brushes
Role: Miniature irregularly shaped contact strips (trapezoidal cross-section + silver alloy cladding)
Problem Solved: Interlayer bonding strength ≥300MPa, surface roughness Ra≤0.8μm, meeting the requirements of high-vibration environments.
Manufacturing Capabilities
Four-roll AGC rolling mill achieves strip thickness tolerance of ±0.005mm; gas-protected bright annealing furnace ensures grain refinement to ASTM 1-2 grade; injection molding machine supports multi-cavity molds (64 cavities) for insert injection molding.
