Blowpipe Solder

With over 30 years of experience in alloy technology, we are one of the UK’s leading tin-lead alloy and lead-free solder producers. Amongst the first in our industry to gain BS5750 Part 2 accreditation, we manufacture a wide variety of products in accordance with both our approved Quality Management System and Environmental Management System.

Our industrial grade blowpipe solder is available in a comprehensive range of high quality, fusible alloys. These ultra-high purity alloys are primarily based on bismuth, tin and lead, as well as the addition of indium, gallium and cadmium where required. Incorporating common alloys melting between 47°C and 183°C, our standard blowpipe solder melts at a relatively low temperature. This characteristic makes these alloys suitable for uses such as:

  • General soldering applications including wiping and joining of lead pipes
  • Optical lens grinding
  • Tube bending
  • Radio therapy shielding

Offering a large selection of low melt alloys and blowpipe solder, our in-house laboratory is fully equipped and able to cater to any individual requirements. For more information about the chemical specifications and physical properties available in our blowpipe solder and low melt alloy range, contact us on 01506 847710.
