ASTM B29 Pure Lead Ingot in China
Grades of lead
Grades are pure lead (also called corroding lead) and common lead (both containing 99.94% min lead), and chemical lead and acid-copper lead (both containing 99.90% min lead). Lead of higher specified purity (99.99%) is also available in commercial quantities. Specifications other than ASTM B 29 for grades of pig lead include federal specification QQ-L-171, German standard DIN 1719, British
specification BS 334, Canadian Standard CSA-HP2, and Australian Standard 1812.
· Lead ingots produced to ASTM B29-03 specifications for refined pure at
99.97% and pure lead at 99.94%
· Lead ingots that tweak the standard purity specifications to include very low sulfur at controlled levels
Purity specifications like those listed above would be used in radiation shielding applications for interlocking lead bricks or nuclear quality pours as well as extrusion lines that require a very consistent lead quality to achieve reliable repeat values.
· *G2 ballast grade lead ingots that would satisfy the requirements of the end user requiring a "heavy metal" lead ballast weight solution
*This material is produced to a 96.5% minimum purity lead level and may contain 1.5-3% Antimony (Sb) and .1-3.5% Tin (Sn)
STANARD METAL IS ABLE TO PROVIDE YOU WITH VERY
SPECIFIC LEAD GRADES SUCH AS:
· Chemical Copper lead
· Low sulfur
· Low bismuth
· Low silver pure lead
· Various alloyed lead ingots produced to meet your specifications, such as 3% antimonial bullion (typically used for sailboat keels) or 6% antimonial bullion(typically used for bullet lead)

Payment: T/ T
Delivery time: About 3 days after your payment ;
Packing: One ton each pallet ,fixed by iron blet ;
Shipping: Tianjin Xingang port, Shanghai port , Qingdao port ;
3. Application :
Ammunition. Large quantities of lead are used in ammunition for both military and sporting purposes. Alloys used for shot contain up to 8% Sb and 2% As; those used for bullet cores contain up to 2% Sb.
Terne Coatings. Long terne steel sheet is carbon steel sheet that has been continuously coated by various hot dip processes with terne metal (lead with 3 to 15% Sn). Its excellent solderability and special corrosion resistance make the product well-suited for this application.
Lead foil, generally known as composition metal foil, is usually made by rolling a sandwich of lead between two sheets of tin, producing a tight union of the metals.
Fusible Alloys. Lead alloyed with tin, bismuth, cadmium, indium, or other elements, either alone or in combination, forms alloys with particularly low melting points. Some of these alloys, which melt at temperatures even lower than the boiling point of water, are referred to as fusible alloys.
Anodes made of lead alloys are used in the electrowinning and plating of metals such as manganese, copper, nickel, and zinc. Rolled lead-calcium-tin and lead-silver alloys are the preferred anode materials in these applications, because of their high resistance to corrosion in the sulfuric acid used in electrolytic solutions. Lead anodes also have high resistance to corrosion by seawater, making them economical to use in systems for the cathodic protection of ships and offshore rigs.
