Key composition factors:
Silver solder exhibits distinctive characteristics that make it ideal for creating strong metallic bonds. Its properties combine excellent flow with reliable joint strength across different temperature ranges.
Silver solder flows smoothly at temperatures between 600°C and 750°C, depending on its composition. Here’s how different types perform:
The silver content directly affects flow behaviour:
| Silver Content | Flow Characteristics |
|---|---|
| 55-56% | Superior capillary action |
| 40-45% | Moderate flow rate |
| 30-35% | Standard flow properties |
Silver solder creates bonds with exceptional tensile strength ranging from 350-450 MPa. These performance features stand out:
The mechanical properties vary by composition:
| Type | Tensile Strength (MPa) |
|---|---|
| Hard | 420-450 |
| Medium | 380-420 |
| Easy | 350-380 |
These joints maintain their integrity across multiple thermal cycles, making them reliable for demanding applications like jewellery making or industrial equipment repairs.

Silver solder creates strong bonds across multiple industries in the UK market. Its versatility makes it a preferred choice for professionals working with precious metals electrical components plumbing systems.
Silver solder excels in industrial plumbing metal fabrication applications. Its high tensile strength (350-450 MPa) creates leak-proof joints in:
| Application Type | Recommended Silver Content | Working Temperature |
|---|---|---|
| Heavy Duty Plumbing | 45-56% | 720-750°C |
| General Fabrication | 30-45% | 670-700°C |
| Light Repairs | 20-30% | 630-650°C |
The rod format (1.5mm-3.0mm) suits larger industrial joints while rings washers work well for pipe connections. Plumbers typically use easy-flowing grades (630-650°C) to minimise heat damage to surrounding materials.
We’ve explored the comprehensive world of silver solder in the UK from its diverse applications to crucial technical specifications. Quality silver solder remains essential for creating reliable bonds in industrial applications.
Whether you’re a professional jeweller or a DIY enthusiast choosing the right type of silver solder is vital for project success. By considering factors like silver content working temperature and application requirements you’ll be well-equipped to make informed decisions.
Remember that investing in high-quality silver solder and proper safety equipment will ensure optimal results in your metalworking projects. With the right supplier and careful attention to specifications you’ll achieve strong durable joints that stand the test of time.

Silver solder is a metal alloy joining material that contains silver mixed with other metals like copper, zinc, or tin. It’s designed for creating strong bonds between metal pieces and is widely used in jewellery making, plumbing, and industrial applications. The silver content varies depending on the type and intended use.
There are four main types: hard, medium, easy, and extra-easy silver solder. Hard silver solder melts at 720-750°C, medium at 670-700°C, and easy at 630-650°C. Each type is suited for different applications, with harder solders providing stronger bonds but requiring higher working temperatures.
Higher silver content results in stronger bonds and higher working temperatures but comes at a higher cost. Lower silver content offers better flow characteristics at a reduced price. The silver percentage also influences capillary action, with higher silver content providing superior flow properties.
Silver solder joints exhibit exceptional tensile strength ranging from 350-450 MPa. They are highly durable, corrosion-resistant, and stable at elevated temperatures. Hard silver solder achieves the highest tensile strength, making it ideal for demanding applications.
Essential safety equipment includes heat-resistant gloves, safety goggles, and respirator masks. You also need proper ventilation and fire-resistant work surfaces. It’s crucial to check gas connections, maintain a clean work area, and store materials safely.
Silver solder is extensively used in jewellery making for creating and repairing pieces, plumbing for leak-proof joints in copper and stainless steel systems, electrical work, and machinery repairs. Its versatility makes it suitable for both delicate and heavy-duty applications.
