Key Features of Grade G Leaded Solder

  • General Application and Plastic Range: A 40% tin, 60% lead alloy suitable for general-purpose hand soldering and torch soldering applications, possessing a broad plastic (semi-liquid) range between its solidus point (183°C) and liquidus point (238°C) that eases joint formation, filling of large gaps, and metal positioning.
  • Wetting Performance: Exhibits good solder flow and wetting performance on copper, brass, and ferrous metals when used with appropriate (rosin or acid-based) fluxes for general electrical and metal fabrication applications.
  • Mechanical Properties: Grade G solder provides moderate mechanical strength ideal for general industrial maintenance and repair applications. While it delivers reliable joint performance in typical operating conditions, it exhibits lower resistance to creep compared to newer solder alloys. This means it is best suited for applications without prolonged exposure to high temperatures or continuous mechanical stress.
  • Industry Standards and Use: Conforms to historical and specific standards for lead-based solder alloys (e.g., ASTM B32 Sn40A, ISO 9453:2014 alloy n° 114) used in non-potable water plumbing, stained glass, and automotive radiator repair, but its use in new commercial electronics manufacturing is restricted in many regions due to the RoHS directive.

Typical Applications for Grade G Solder

Grade G solder alloy suits a wide range of applications including electrical component assembly, plumbing repairs, metalwork fabrication, and general industrial soldering tasks. Its higher tin content and plastic phase characteristics make it popular among manufacturers and maintenance engineers who require consistent, strong, and reliable solder joints.

Frequently Asked Questions

What are the alternative names for Wood’s Metal? +

Low Melt 70 is known globally by several industry trade names. Depending on your region or legacy technical specifications, it may be referred to as:

  • Cerrobend
  • WR Bendalloy
  • Ostalloy 158
  • Fry’s Fusible No 2

DKL Metals manufactures this alloy to meet the eutectic 70°C specification required for these trade names.

How do you use a low melting point alloy for tube bending? +

To prevent kinking, the low melting point alloy for tube bending is melted and poured into the tube. Because it expands upon cooling, it provides internal support. Once the bend is complete, the assembly is placed in hot water to safely melt and remove the alloy for reuse.

Is this the correct fusible alloy for fire sprinkler systems? +

Yes. Low Melt 70 is a primary fusible alloy for fire sprinkler systems and safety thermal links. Its eutectic nature ensures it remains completely solid until it reaches 70°C, providing a reliable and rapid release mechanism.

What is the Bismuth-based alloy dimensional stability after casting? +

A key feature of Bismuth-based alloy dimensional stability is its unique growth property. Unlike most metals, this alloy expands by approximately 0.51% within one hour of casting, ensuring a tight mechanical grip for machining fixtures and tooling.

Where to buy Wood’s Metal in the UK for industrial use? +

If you are looking for where to buy Wood’s Metal in the UK, DKL Metals manufactures high-purity fusible alloys at our Grangemouth facility, supplying formats from 85g blowpipe strips to 1kg bars.
