Special Alloys Components

Die Casting

Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process.

Alloys Required

CuNiSiCr
CuCoNiBe
CuNiBe
CuBe2

Available Sizes

From dia 40 mm and above high pressure die casting pistons and plunger tips in semi finished or finished (according to drawing) forms.

Mould and Dies

Injection moulding is a manufacturing process for producing parts by injecting material into a mould. Injection moulding can be performed with a host of materials mainly including metals. Material for the part is fed into a heated barrel, mixed, and forced into a mould cavity, where it cools and hardens to the configuration of the cavity.

Alloys Required

CuCoNiBe
CuNiBe
CuBe2

Available Sizes

rough, semi finished or finished (according to drawing) forms.

Resistance Welding

Seam Welding Wheels

Seam welding produces an extremely durable weld because the joint is forged due to the heat and pressure applied. A properly welded joint formed by resistance welding can easily be stronger than the material from which it is formed.

Alloys Required

CuCoNiBe
CuCrZr
CuCoBe

Available Sizes

Up to 560 mm. wheels in semi-finished or finished forms according to drawing.

Mesh Welding (Cross Wire) - Multispot Welding - Butt Welding Electrodes Parts

Resistance welding is a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current. It is a subset of electric resistance welding

Alloys Required

CuNiSiCr
CuCoNiBe
CuBe2
CuCrZr

Available Sizes

rough, semi finished or finished (according to drawing) forms.

Aluminium Bronze Applications

Aluminium Bronze Applications

Aluminium bronze is a type of bronze in which aluminium is the main alloying metal added to copper, Aluminium bronzes are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. These alloys are tarnish-resistant and show low rates of corrosion in atmospheric conditions, low oxidation rates at high temperatures, and low reactivity with sulfurous compounds and other exhaust products of combustion.

Alloys Required

CuAl10F3Mn
CuAl10Ni5Fe4
CuAl14Fe4Mn2

Available Sizes

rough, semi finished or finished (according to drawing) forms.

Copper Nickel Applications

Copper Nickel is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. It is highly resistant to corrosion by salt water, and used for piping, heat exchangers and condensers in seawater systems, as well as for marine hardware. It is also used for the propellers, propeller shafts, and hulls of high-quality boats. Other uses include military equipment and chemical, petrochemical, and electrical industries.
