SAVES – SCRAP OF OLD ZINC MATRIX CASTINGS
Consist of different old matrix castings with content of zinc, with or without iron and other supplements. To be without drilling cuttings, cinder particles, large and melted particles and slag consisting arsenic. All not-melting, polluted and other supplements as well as volatile substances (as rubber, cork, plastics, grease etc.) be taken (deduct). Material containing iron above 30% is not considered suitable for delivery.
SCABS – SCRAP FROM OLD ZINC MATRIX CASTINGS
Consist of new or not used clean zinc matrix castings with metal coating, which have no corrosion.
SCOPE – SCRAP FROM ZINC MATRIX CASTINGS WITH METAL COATING
Consist of new or not used zinc matrix castings with metal coating and with no corrosion.
SCOOT – ZINC CAR GRID CASTINGS
Consist of old or not used casted car grids of zinc base without solder material. All other supplements and materials are taken (deducted).
SCORE – ZINC SCRAP
Consist of clean dry zinc scrap such as sheets, lids of containers, clean and non-alloy castings and anticorrosion coverings. Drilling cuttings and hidden particles are not accepted. The material should not have too much corrosion or be oxidised. All other additives and ancillary materials shall be deducted.
SCREEN – NEW ZINC CLIPPINGS
Consist of all types new clean zinc sheets or particles from molded products which have no corrosion. Not to consist of other materials or supplements. Zinc for printing such as zinc for engraving machines, lithographic plates and engraved address plates are subject to additional agreement. Zinc printing is without profile milling elements.
SCULL – FLAT MATRIX CAST BILLETS OR INGOTS
Consist of melted flat matrix zinc materials on smooth, clean hard billets or ingots. The material is without cinder and with min. 90% contents of zinc. A maximum content of nickel is 0.1%, and maximum lead contents – 1%. Blocks are allowed by mutual agreement.
SCRIBE – SCRAP OF MATRIX CAST SORTED AND SPLIT IN SHREDDER MATERIAL OBTAINED IN CAR SHREDDERS
Material is clean, with repelled contaminants, and no glass, rubber and litters. To consist of maximum 5% not melting particles such as iron, copper, aluminum and other metals.
SCROLL – UNSORTED SCRAP OF ZINC CASTINGS
It is produced in car shredders. The material is scrap with around 55% content of zinc. Other non-ferrous metals such as aluminumр stainless steel, red metal, etc. are around 40%. Insulated copper wire about 1%. Content of waste, dirt, glass, rubber, grease, iron is not more than 5%.
All deviations are traded under a separate agreement between buyer and seller.
SCRUB – ZINC CINDER OF FLAT CASTINGS FROM GALVANIZATORS WITH HOT SOLUTION (complex technology)
Consists only of unseparated zinc cinder from galvanizators in the form of a flat casting of hot galvanization (complex technology) with a minimum zinc content of 92% without arsenic butt and occasional metal impurities. Splintery pieces under 2 inches in diameter may not exceed 10% of weight of each batch. Flat castings are not more than 100 pounds each. Heavier cuts are allowed by mutual agreement between buyer and seller.
SEAL – ZINC CINDER OF FLAT CASTINGS FROM THE SURFACE OF A LINE FOR CONTINUOUS GALVANIZATION.
Consist of not separated by melting zinc cinder, separated from the surface of the tub for continuous galvanization under the form of flat castings, but not heavier than 100 pounds each, with minimum 90% contents of zinc. Heavier cuts are allowed by mutual agreement between buyer and seller. To have no butt of slag. Splintery pieces less than 2 inches in diameter may not exceed 10% by weight of each batch.
SEAN – ZINC CINDER OF FLAT CASTINGS FROM THE BOTTOM OF A LINE FOR CONTINUOUS GALVANIZATION
Consist of not separated by melting zinc cinder, separated from the surface of the tub for continuous galvanization under the form of flat castings, but not heavier than 100 pounds each, with minimum 92% contents of zinc. Heavier cuts are allowed by mutual agreement between buyer and seller. To have no butt of slag. Splintery pieces less than 2 inches in diameter may not exceed 10% by weight of each batch.
SHELF – CINDER OF PRIMING ZINC MATRIX CASTINGS
It consists of a metal slag of the cover of boiler for melting zinc matrix castings. Not separated by melting, it is not mixed with stock, is metallic shining, and the metal is not oxidised or has corrosion. It is run into molds or into small cubes no more than 75 pounds each. Zinc is 85% min.
