10 PCS 900M-T-1.2D Small D Type Lead-free Electric Welding Soldering Iron Tips are designed for use with soldering irons. They provide effective heat conduction for soldering tasks.
Material composition: copper, iron, nickel, chromium, tin
Copper provides good thermal conductivity
Iron offers corrosion resistance
Nickel prevents rust in iron plating
Chromium prevents tin from running on the iron head
Tin is used in the sticky tin parts of the head
Long service life
Good tin effect
Requires cleaning after each use
Low active flux is recommended to reduce corrosion
Proper size and shape selection is crucial for efficiency
Size affects thermal capacity
Flat, blunt iron heads transmit more heat than sharp ones
