Lead Alloy Manufacturer In India

Because of the fact that lead is extremely soft

, elastic and ductile, it is commercially used in the form of lead alloys. Its common elements of alloying are Tin, Calcium, Arsenic and Antimony.

Antimony is generally used for providing greater strength and hardness which is required in sheets, pipes, castings and storage battery grids. Arsenic lead is used in chemical sheathing as Arsenic is able to harden the lead-antimony alloys and is required in the production of a round dropped shot. Lead-antimony alloys have been replaced by Lead-Calcium alloys in many applications, especially in casting applications and storage battery grids. Recently, Aluminum is added to Calcium-Tin-Lead and Calcium-Lead alloys to work as stabilizer for the Calcium.

By adding Tin to the Lead and its alloys, it becomes helpful in increasing its strength and hardness and the lead-tin alloys are commonly used for their properties of good melting, wetting and casting, as in solders and type metals. As unalloyed Lead does not have good wetting properties, Tin gives it an ability to easily wet and also bond with the metals like Copper and Steel.

Types of lead alloys

The lead alloy manufacturers in India manufactures both kinds of lead alloys which are head lead and soft lead. Soft lead is the pure lead is a lead alloy. One or more metals are added to soft lead in order to make it harder and thus capable of molding.

Procedure of manufacturing lead alloys

With the help of state-of-the-art plants, a lead alloy manufacturer in India like www.mettradeindia.com is able to manufacture different lead alloys in accordance with stringent determined specifications such as calcium, selenium, antimony, and arsenic. The kettle pots in the plants range from 20 to 100 metric tones per batch in capacity and are accompanied by highly efficient furnace oil burners having arrangements of pre-heating.

The process of alloying is performed under control of spectrometer and the conclusions are confirmed via alternative methods of analysis such as atomic absorption spectrophotometer and web analysis. By making continuous investment in the plant and the technical resources, the service requirements and diverse applications are met effectively.

Precautions while manufacturing lead alloys

When poured in a mold, a lead alloy will freeze or solidify at certain temperature while soft lead or pure lead will still be fluid. While manufacturing hard lead, a lead alloy manufacturer must keep in mind that it requires more efforts and experimentation than pure lead and it can work well for certain large and medium lures and sinkers. But its usage should be avoided in difficult to mold spinner baits and small jigs. It should not be used for making sinkers such as pinch-on types and split shot types. Lead alloys will make such sinkers extremely stiff that they will not be able to bend and work correctly.
