900M-T-I Type Pure Copper Soldering Iron Tips for Soldering Station Tool This is a super sharp type ideal for detailed workmanship, soldering in narrow spaces, or repairing tin bridges from chip soldering. These iron tips are made of pure copper without electroplating, making them easy to tin and diamagnetic, suitable for low-temperature soldering. Avoid leaving the iron powered on for extended periods when not in use, as this may cause the tip to develop a black oxide layer. Always tin the tip while it is heated. Prolonged heating or excessive temperatures will cause the solder to burn off and the tip to turn black.
