Copper and Copper Alloys form an important group of metals with many excellent properties. They have very good electrical and thermal conductivities, offering twice the conductivity of Aluminium and thirty times the conductivity of Stainless Steel. Copper Alloys have high ductility and are easy to fabricate, with ease of brazing and solderability. This group has many advantageous characteristics and includes alloys of exceptional strength (notably Copper Beryllium Alloys), corrosion resistance, and antimicrobial properties. The characteristics of Copper and Copper Alloys have resulted in extensive use of those alloys in a very wide range of applications. Copper is most commonly used in electrical and electronic applications, accounting for half of the Copper produced today. These Alloys can be formed, pressed, deep drawn or photochemically etched into the most complex of shapes.
In general terms, the important commercial alloy groups are:
Our high conductivity copper products feature 99.9% copper content, offering:
The coppers within this group have differing degrees of purity and consequently exhibit different characteristics. For high conductivity requirements, such as electrical components, Oxygen-free Coppers are required. The extra purity enhances ductility and gives freedom from Hydrogen embrittlement or blistering during brazing operations.
Applications: These grades are ideal for electrical components, busbars, terminals, and heat exchangers where maximum conductivity is essential.
Available Grades:
Commercially Pure (High Conductivity)
Commercially Pure (Medium Conductivity)Â
High Content Copper Alloys
These alloys retain a high copper content (94-99%) while incorporating small amounts of alloying elements to enhance specific properties:
We supply Cu-DHP (Deoxidised High Phosphorus Copper) in precision strip and wire and Alloy 194 is available in precision strip. Both offer an optimal balance of conductivity and mechanical strength, making them ideal for demanding applications requiring a balance of conductivity and mechanical strength.
Available Grades
Brasses are Copper based alloys with Zinc as the essential secondary ingredient. The addition of Zinc to Copper creates a lower cost alloy with superior cold working strength to Copper but at the expense of reduced conductivity. The degree of alloying gives a varying range of properties that include strength, hardness, thermal and electrical conductivity, corrosion resistance, machinability, and ductility. The difference in alloying also creates a range of colours, ranging from red, yellow, gold, bronze, silver and brown, consequently making Brass ideal for decorative applications. Additionally, Brass is used in a wide range of applications, including Precision Stamping and Processing. Thanks to antimicrobial properties, they are highly beneficial in hospital environments and brewery facilities. An additional benefit of Brass is its recycling ability.
Our brass alloys deliver:
Applications: Brass alloys are widely used in electrical connectors, terminals, hardware, and decorative applications.
Available grades:
Phosphor Bronze is a Copper Tin alloy, often referred to as Phos Bronze or Tin Bronze. These alloys contain up to 7% Tin and a small quantity of Phosphorus, which is a residual from the deoxidation of the Copper melt before the addition of Tin. By increasing the Tin content, you can increase the corrosion resistance and improve the strength of the alloy.Â
The alloys in our copper phosphor bronze range offer:
Additionally, Phosphor Bronze offers good wear resistance, and thermal and electrical conductivity and can be significantly hardened by cold working to give excellent spring properties.Â
Applications: This Alloy dates back over 4000 years, when it could be found in weapons, armour, tools and decorative items such as jewellery. In modern manufacturing phosphor bronze is used in many applications, notably in the Marine, Chemical and Aerospace Sectors. Key applications include springs, electrical contacts, fasteners, and precision components requiring resilience.
Available Grades:
Nickel Silver Alloys
Unlike the name suggests, Nickel Silver alloys do not actually contain any Silver. This group of alloys take their name from their silvery appearance, created from a carefully balanced composition of copper (typically 55-65%), nickel (10-18%), and zinc (17-27%). With a desirable look that mimics Silver, these alloys can be polished to a high lustre, resulting in their wide use for adding decorative finishes to products, including jewellery, tableware and musical instruments. Their mechanical properties are somewhat similar to Brass Alloys. However, the addition of Nickel provides superior resistance to stress corrosion cracking and tarnishing.
Key Features of Nickel Silver Alloys:
Applications: Nickel Silver is suitable for many applications and can typically be found in electrical contacts, springs, decorative elements, and musical instruments.
Available grades:
Cupronickel
Cupronickel alloys contain 10-30% nickel and no zinc, setting them apart from nickel silvers. The most popular cupronickel grades are those with a content ratio 90/10 Copper Nickel and 70/30 Copper Nickel. 90/10 is more common as it is less expensive and has a good overall balance of properties, whilst 70/30 has greater saltwater resistance and strength. Known for exceptional corrosion resistance, cupronickel has been used in marine environments for over a century.
Nickel forms a solid solution with copper, preventing dezincification and stress corrosion cracking. A stable oxide layer enhances resistance to pitting, crevice corrosion, and biofouling.Â
These copper-nickel alloys feature:
Applications: Cupronickels exhibit excellent formability and remarkable resistance to seawater corrosion, making them suitable for marine and offshore applications. Beyond their corrosion performance, cupronickels maintain good thermal conductivity and weldability, making them invaluable in heat exchanger applications.
Available Grades:
Beryllium Copper
Beryllium Coppers are a group of high-performance copper-based alloys with exceptional mechanical properties and the essential electrical and thermal conductivity characteristics of copper. These alloys exhibit an extraordinary combination of properties including exceptional fatigue resistance, elasticity and non-sparking characteristics making them suitable for pressure responsive components such as spring applications and ideal for safety-critical applications. This makes them indispensable for a number of demanding industry sectors such as Petrochemical, Oil and Gas and Mining.Â
These sophisticated alloys typically contain 0.4-2.0% beryllium with small additions of other elements such as nickel, cobalt, or titanium that act as catalysts in the precipitation hardening process. What distinguishes beryllium copper is its remarkable response to age hardening treatments—a carefully controlled thermal process that enables these alloys to achieve tensile strengths exceeding 1400 MPa while maintaining electrical conductivity up to 45% IACS. The microstructural evolution during heat treatment involves the formation of nanoscale beryllide precipitates (primarily CuBe) that effectively impede dislocation movement, dramatically increasing strength and hardness.
Our premium high-performance alloys offer:
Applications: Used in critical applications including electrical connectors, springs, moulds, and safety tools. Beryllium Copper is also increasingly machined into miniaturised components, which are required by electronics and telecommunication manufacturing for everyday items such as mobiles, laptops, and tablets.
Available Grades
We can supply these alloys in the following forms:
i) Solution treated (Annealed), or
ii) Solution treated & temper rolled, i.e. 1/4 Hard, 1/2 Hard, Hard, etc.
