Copper alloys are copper-based alloys.
They have excellent corrosion resistance, strength, and workability.
We Enserve offer copper alloys with 4 distinct advantages for you. Based on our advantages, our copper alloys have been delivered to global leading companies in Japan, Europe, and US.
We would be happy to find your desired copper alloy, based on your expectation of QCD (Quality, Cost, Delivery). For standard copper alloy, MOQ is from 500kg, for customized, original copper alloy, we can arrange from 1000kg. For any details (chemical composition or mechanical / physical properties) or consultations (delivery from stockyard, price inquiry), please contact us.
Enserve handles rare / exotic copper alloy types / shapes / dimensions that you might not be able find in your region. Our copper alloys are made from a melting pot and processed with special shapes. We handle Beryllium Copper, Chromium/Zirconium Copper, Aluminum Bronze, Corson Alloy, Cupronickel & Nickel Silver.
Enserve’s copper alloys have many delivery records to European / American market leaders due to high quality. Enserve’s copper alloys are certified for ISO9001 (Quality), ISO14001 (Environment), ISO45001 (Health & Safety), AS9100 (Aerospace, equivalent to JISQ9100). Particularly, AS9100 is difficult to obtain and owner of AS9100 is often considered as a proof of high quality.
Enserve’s copper alloys are price competitive due to locally produced law material, relatively low cost of labor and energy. As a result, Enserve’s copper alloys have been used by many Western European and American companies.
Enserve’s copper alloys are fast to deliver. Our copper alloys Lead Time from an order to shipment is about 3 months. If you wish, Enserve can also deliver from a nearest stock yard for 2~3 days delivery. Our arrangement makes your business much more flexible for demand changes.
Beryllium Copper is a copper alloy with 0.5 – 3% beryllium and sometimes other metals. Beryllium copper has high strength, high heat conductivity, corrosion resistance, high electrical conductivity, and is non-magnetic and non-sparking. It is also suitable for metalworking, forming, and machining. Beryllium is toxic for human body and may be restricted at your location (for example in a region in Japan, a user of Beryllium, who annually processes Beryllium 500kg or more, must declare in advance).
Beryllium copper is the strongest among copper alloys. Beryllium copper has tensile strength of min 650-min 1100 N/mm2 or Brinell Hardness (HB30) of min 210- min 336. This strength is about 90% of SKD61 (typical tool steel).
Beryllium copper has thermal conductivity of 105-240 W/m. K and is used in applications requiring highly efficient heat dissipation. Beryllium copper has 3~7 times higher thermal conductivity than iron. The use of beryllium copper enables high-cycle production by reducing the heating and cooling time.
Beryllium copper can protect the metal inside by creating a type of rust on its surface called a passive film. Although corrosion cannot be completely stopped, it can be controlled to a fairly low level. Mean while, even corrosion resistant steel such as stainless steel causes crevice corrosion (Phenomenon of preferential erosion between metals).
Beryllium copper has electrical conductivity of 24-42% (IACS) or 15-24 (MS/m). Beryllium copper is used in applications requiring high current density.
Beryllium copper has non-magnetic and non-sparking property, which is important for oil & gas industry.

Aluminum Bronze is a copper alloy with 5-12% of aluminum and other metals such as iron, nickel, and manganese. Aluminum Bronze copper has high strength, lightweight, corrosion resistance and wear resistance.
Aluminum Bronze has tensile strength of min 485- min 896 N/mm2 or Brinell Hardness (HB30) of min 81- min 256. This is more than double the strength of standard bronze.
Aluminum Bronze is the lightest weight among copper alloys. Aluminum Bronze has density of 7.6-7.9 g/cm3. Other copper alloy’s density is 8.3-8.9g/cm3.
Aluminum Bronze is metallographically and chemically resistance to acids and seawater.
Aluminum Bronze’s metal structure is uniform both on the surface and inside, and the β-phase is finely distributed in the α-phase, so it retains oil well and has very good wear resistance.

Corson alloys are special copper alloys with Ni and Si as major sub-components. Corson alloys are characterized by high strength, high heat conductivity, and high electrical conductivity. For Corson alloys, annealing (property change by heat) occurs at a higher temperature than that of phosphor bronze, so mechanical properties are not easily lost even at high temperatures (around 700℃).
Corson alloys have tensile strength of min 400-675 N/mm2 or Brinell Hardness (HB30) of min 90-160.
Corson alloys have thermal conductivity of 200-260 W/m.K and is used in applications requiring highly efficient heat dissipation. Corson alloys have around 6~7 times higher thermal conductivity than iron. The use of Corson alloys enable high-cycle production by reducing the heating and cooling time.
Corson alloys have electrical conductivity of min 43-57% (IACS) or min 25-39 (MS/m). Corson alloys are used in applications requiring high current density. Pure copper has electrical conductivity is 100% (IACS) or 56 (MS/m). Considering other properties (such as hardness), Corson alloys are used.

Cupronickel is special copper alloy with 10-30% Ni as notable sub-components. Those with high nickel content have a white luster similar to silver and are used as a substitute for silver in coins and other items. It is also hard and has excellent ductility, heat resistance, and corrosion resistance.
Nickel silver is a special copper alloy with 19~27%Ni, and 1~9% Zn as notable sub-components. Nickel silver is a beautiful silvery-white color, and has excellent ductility and relatively high corrosion resistance.
Both Cupronickel and Nickel Silver contain high amount of Ni which makes these copper alloys silvery white color.
The high amount of Ni makes both Cupronickel and Nickel Silver highly corrosion resistant.
