Base Alloy

We supply base alloys that are produced on site at our foundry in Birmingham to both industry standards and tailor made to customers own requirements where practical.

Base alloy is one of the eutectics, i.e. it has a sharp melting point (124°C). Unlike bend alloy, tool alloy and press alloy, which expand immediately on solidification, base alloy first shrinks and then grows slowly, reaching the dimensions of the mould some 5 - 7 hours after casting. This characteristic is of value since castings can be removed easily from the mould and measurements taken accurately when the casting has reached mould dimensions. It is also useful as a bending medium instead of bend alloy where the latter's expansion characteristic is too great. Base alloy is manufactured from virgin metals and is guaranteed to give complete satisfaction under normal working conditions.

Bend Alloy

Efficient supply of bend alloy tailored to your specific needs

William Rowland Limited is able to produce a wide range of low melting point alloys at our foundry in Birmingham. All of our low melting point alloys are compliant with industry standards. We are also able to produce alloys that are tailored to meet our customers’ specific requirements.

One type of low melting point alloy William Rowland produces is bend alloy: WR 70.

WR 70 bend alloy, a low melting point alloy

Bend alloy is one of the most extensively used alloys in industry. Part of the widespread need for bend alloy is due to its primary characteristic of expansion on solidification from the molten state. This makes bend alloy an ideal material to support metal tubing with thin walls during bending operations.

The alloy has a sharp melting point of 70 degrees Celsius and can consequently be melted with hot water.

Professional and credible supplier of bend alloy

Casting Alloy

Quality casting alloy supply with William Rowland

Casting alloys are a range of low temperature alloys based on tin, lead or bismuth that are suitable for production of jewellery, models, figures, artwork, collectibles, ornaments and memorabilia.

William Rowland produces many different grades of casting alloy to suit the customer’s process and production requirements, however we will also produce to a customer’s individual specification. Our casting alloys are suitable for the professional or hobbyist and we produce many grades that are safe and easy to work with using only the minimum of basic equipment.

Lead-free pewter alloys are popular for jewellery, artwork and collectibles where reproduction of fine detail and cast finish are important, as well as being safe for human contact . These alloys are commonly high in tin and alloyed with copper and antimony. As-cast finish is very good and cast objects polish very well to a silver lustre.

For applications in which lead can be tolerated, the range of alloys is extensive, generally providing cheaper alloys but ones which can be tailor-made for specific purposes such as thin or bulky items, reproducing fine detail, malleability or achieving a particular surface finish. These alloys commonly contain tin, lead and bismuth but may also contain antimony and zinc.

William Rowland casting alloys are suitable for a range of casting techniques such as centrifugal and gravity casting into rubber or silicon moulds.

Efficient casting alloy delivery with first-rate customer service

William Rowland prides itself on the supply of alloys and other metal products, professionally, efficiently and cost-effectively. All of our casting alloys are made from primary metals in our onsite foundry in Birmingham, they can be adapted to customer requirements as needed.

Global distribution of casting alloy

Fusible Alloy

William Rowland are specialists in the delivery of fusible alloys

Looking for high-quality fusible alloy? Look no further than William Rowland, specialists in the metals trade and distributing alloys and other metals around the world.

Fusible alloy is essentially a type of metal alloy which can be fused with ease. These metal alloys can be melted at temperatures that are relatively low. They are typically eutectic alloys, meaning they have a sharp melting point.

Fusible alloys are often used as the term to describe alloys that have a melting point which is below 183 degrees Celsius.

What are fusible alloys used for?

Fusible alloys are irreplaceable in a range of applications where their low melting point is fundamental:

Tube and profile bending

Work holding of delicate or irregular pieces

Fusible cores for plastic or composite moulding techniques

Fusible plugs for boilers and pressure vessels

Fusible safety devices for fire prevention such as sprinklers

Lens blocking

Rapid prototyping of press tools

Fusible alloy distribution

William Rowland Limited can supply fusible alloys around the world. Experienced in the manufacturing and distribution of fusible alloy, we will ensure your metal alloy requirements are delivered to you safely for a competitive price.

One fusible alloy we can deliver without delay is bend alloy, one of the group of bismuth based alloys with a low melting point. Bend alloy is the most widely used fusible alloy in industry.

Our fusible alloys can be tailor made to cater for your individual circumstances and requirements.

If you require the use of fusible alloy and would like to discuss your requirements, get in touch with the William Rowland team, specialists in fusible alloy distribution.

William Rowland are specialists in the supply of lens alloys. Our high-quality lens alloys are produced at our foundry in Birmingham. All of the lens alloys produced by William Rowland can be made to our customers’ specific requirements. Our metal products, including our lens alloy, comply with industry standards.

Lens alloys are part of the group of bismuth-based ‘fusible’ alloys. Indium is added to the alloy in order to give it a considerably lower melting point

A sharp melting point

William Rowland lens alloys are eutectic alloys, characteristically possessing a sharp melting point at 58 or 47 degrees Celsius.. This low temperature is ideal for acting as a ‘button’ or holding medium in the grinding of lenses.

Possessing stable characteristics, and being easy to melt, lens alloy can be reused repeatedly if required.

Primary use of lens alloy

The primary use of lens alloy is in grinding operations when it proves invaluable in holding glass or plastic lenses. Due to its low melting properties, lens alloy is also a suitable component in the fuses of safety equipment. Lens alloy can also be effective in proof casting.

Having been in operation for more than 180 years, William Rowland is one of the oldest traders of lens alloy and other metal products in the world.

Press Alloy

We supply press alloys that are produced on site at our foundry in Birmingham to both industry standards and tailor made to customers own requirements where practical.

Press alloy is one of the eutectics, i.e. it has a sharp melting point (138°C) and like the majority of bismuth based alloys it expands on solidification. This material is free flowing and its versatility makes it a unique tool in a great variety of industries. Its low melting point ensures easy and safe handling and under normal conditions it can be re-used almost indefinitely. Press alloy is manufactured from virgin metals and is guaranteed to give complete satisfaction under normal working conditions.
