10 PCS 900M-T-3.2D Big D Type Lead-free Electric Welding Soldering Iron Tips are designed for use with soldering irons. They provide effective heat transfer for soldering applications.
Type: 900M-T-3.2D Big D Type
Material Composition: Copper, Iron, Nickel, Chromium, Tin
Heat Conductivity: Copper (85% of material) provides good thermal conductivity
Corrosion Resistance: Iron acts as an anticorrosion agent
Durability: Long service life with good tin effect
Nickel: Provides anti-rust properties
Chromium: Prevents tin from running on the iron head
Maintenance: Requires cleaning with a wet sponge after each use
Oxidation Prevention: Keeping tin on the welding head reduces oxidation
Flux Recommendation: Use low active flux to minimize corrosion
Size and Shape: Important for efficiency and durability
Thermal Capacity: Larger heads have higher thermal capacity
Welding Efficiency: Proper geometry improves contact with solder joints
