Special-Shaped Lead Brick Heavy Industry Lead-Antimony Alloy
Product Description
An antimony-containing lead alloy used in the manufacture of grids and conductive parts for lead-acid batteries. Compared with pure lead, it has a lower melting point, good fluidity in molten state, easy casting and molding, and high hardness after solidification; the disadvantage is that the gas evolution overpotential of the grid is low. In order to reduce the precipitation of gas during charging of the battery, reduce self-discharge and improve corrosion resistance, the antimony content has been gradually reduced from the traditional 5% to 7% to about 2% or even lower. At the same time, a small amount of other components such as tin, arsenic, sulfur, selenium and copper are selectively added to improve the physical and chemical properties of the alloy.
Welding temperature 287℃-294℃. According to the welding temperature, the composition ratio is also different.
Physical:
Lead (Pb99) : melting point 327℃, density 11.34g/cm3.
Tin (Sn99.95) : melting point 232℃, density 7.29g/cm3.
Antimony: melting point 630℃, density 6.62 g /cm3.

Features
- Durable
- Malleable
- Low melting point
- Long life-span (in milder climates, lead roofs have been known to last 200-300 years)
- Generally corrosion-resistant - has little to no reaction with most compounds and solutions.
- Resistant to corrosion by most acids including chromic,sulfuric, sulfurous and phosphoric acids.
- Corrosive to alkalis (such as lime mortar, portland cement and uncured concrete), tannic acid found in wood, and radiation.
- Corrosive to hydrochloric, hydrofluoric, acetic, formic and nitric acids.
Applicable
- Roof panels
- Decorative spandrel
- Gutters, Outlets and Downspouts
- Cast decorative features and sculptures
- Domes, spires and mullions
- cable jacket
- Lead-based paint: Red lead is typically used as a corrosion inhibitor for use on iron. White lead is used more frequently in commercial applications. White lead is not intended for use on iron
