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.
WE SUPPLY:
· 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)
