Products classified under HTS 7405.00.10.00
Phosphor Copper Master Alloy Ingot 10% P
Master alloy ingots composed primarily of copper with 10% phosphorus content by weight, used in non-ferrous metallurgy for deoxidizing and grain refining. Classified under HTS 7405.00.10.00 due to phosphorus content between 5-15% and its role as a copper master alloy per Chapter 74 notes. Supplied in standard 25kg ingots for foundry addition.
CuP8 Phosphor Copper Alloy Shot 8% Phosphorus
Granular shot form of copper-phosphorus master alloy with 8% P, ideal for precise dosing in copper and copper alloy melts. Falls under HTS 7405.00.10.00 as it meets the 5-15% phosphorus threshold for copper master alloys. Commonly used in plumbing brass production for improved castability.
Phosphor Copper 12P Master Alloy Waffle Blocks
Waffle-shaped blocks of Cu-P master alloy containing 12% phosphorus, designed for easy melting and uniform distribution in large copper foundry ladles. HTS 7405.00.10.00 classification based on phosphorus over 5% and master alloy function. Preferred form for high-volume brass and bronze casting operations.
Deoxidizer Cu-10P Alloy Sows 10% Phosphorus
Large sow castings of copper-10% phosphorus master alloy used primarily as deoxidizer in copper alloy production. Meets HTS 7405.00.10.00 criteria for 5-15% P master alloys. Essential for preventing oxygen porosity in premium bronze castings.
Brass Foundry Phosphor Copper 7% P Cylinders
Cylindrical castings of 7% phosphorus copper master alloy optimized for brass foundry applications. Classified HTS 7405.00.10.00 for 5-15% P content in copper master alloys per Chapter 74 definitions. Provides excellent fluidity and deoxidation in high-zinc brass melts.
Master Alloy CuP11 Phosphorus 11% Ingots
High-purity Cu-11P master alloy ingots for precision alloying in electrical copper applications. HTS 7405.00.10.00 due to 11% phosphorus content within specified range for copper master alloys. Used where controlled deoxidation is critical for conductivity.
Grain Refiner Phosphor Copper 6% P Pellets
Pelletized form of 6% phosphorus copper master alloy serving as grain refiner in continuous casting. Falls under HTS 7405.00.10.00 for 5-15% P master alloys. Pellets ensure consistent addition rates in high-speed billet production.
Cu-P 9% Master Alloy Broken Fragments
Broken fragments of 9% phosphorus copper master alloy from sow cutting, sold for small batch foundries. HTS 7405.00.10.00 classification unchanged by physical form for 5-15% P master alloys. Economical for artisan bronze casting operations.
