CuP Alloys

CuP Alloys: silver solder and brazing supplies from Nottinghamshire

CuP Alloys is a British supplier of silver solder, brazing alloys and fluxes that has been trading since 1981, according to its own presentation. The company describes itself as a specialist in metal joining materials and positions its offer around both the catalogue of consumables and the technical guidance that accompanies it. Its stated customers range from model engineers and hobbyists to professional craftsmen.

The business presents itself as a UK brazing specialist and states that it combines decades of experience with a focus on product quality and customer service. The catalogue is organised by working temperature and by application, which structures how a buyer navigates the range.

Silver solder ranges by working temperature

The core of the catalogue is a set of cadmium-free silver solder families, each aimed at a different balance of heat and precision:

• Low temperature silver solder: presented as a range designed for precision joining.
• Medium temperature silver solder: described as offering a balance between the extremes.
• High temperature silver solder: engineered for demanding applications.
• Other silver solder: specialist alloys for specific joining requirements.
• Refrigeration silver solders: selected for copper and copper-alloy joints.

Alongside these, the company lists soft solders for applications where lower working temperatures are required, and copper phosphorous brazing rods intended primarily for joining copper.

Fluxes, torches and ancillary equipment

Beyond the filler metals, CuP Alloys stocks the supporting products needed to complete a brazing job. The range includes soft solder fluxes, formulated to remove surface oxides and promote wetting, and silver solder fluxes for brazing applications. It also carries torch kits described as complete heating solutions for brazing, soldering and general heating work, and a line of Sievert® heating equipment covering professional-grade burners, torch handles and neck tubes. A further category of brazing ancillaries groups the supporting items required to achieve a finished joint.

Industries served

The company names four main sectors among its customers: refrigeration, HVAC, automotive and model engineering. The refrigeration line is the most explicitly differentiated in the catalogue, with alloys chosen for copper and copper-alloy work, while model engineering appears repeatedly as a reference point for the smaller-scale end of the range.

Guidance and published material

CuP Alloys presents technical support as part of its offer. The site includes a "Help Me Choose" tool aimed at newcomers to brazing, together with sections on the history of brazing, best brazing practice and health and safety. The company also publishes a brazing handbook, A Guide To Brazing And Soldering by Keith Hale, listed at £24.00. Its catalogue at the time of writing included 455 silver solder rods of 1.0 mm and 1.5 mm diameter in 500 mm lengths, 455 silver solder wire sold by the metre, and a broader selection of rods, wires and pastes described as engineered for flow and gap-filling performance.

Commercial terms and exhibitions

Orders are shipped within the United Kingdom with no minimum spend, and the company states that volume discounts apply to selected rods and wire. CuP Alloys also attends trade events; a notice on the site indicated that orders would ship after the company's return from the Midlands Model Engineering Exhibition on Monday 19 October. The site lists prices in pounds sterling and offers a country selector for international customers.
