Product Range and Specialties of WTZ Gmbh

The product list covers primary metal forms and downstream industrial chemicals. Aluminum ingots are typically supplied in standard ingot sizes ranging from 5 kg to 25 kg and meet purity levels of 99.5 % - 99.9 % Al, while copper scrap is usually classified by grade (e.g., 99 % Cu) and presented in 1‑ton bales. Urea fertilizer at 46 % nitrogen is a standard grade for agricultural use, and the NPK blends follow the indicated nutrient ratios for balanced crop nutrition. Petroleum coke variants (calcined, semi‑graphite, graphite, foundry and metallurgical) are offered in bulk bags or bulk ship loads, with typical moisture contents below 2 % and ash levels under 5 %. Silicon carbide (SiC) is supplied in powder or granule form with particle sizes from 5 µm to 30 µm and purity around 99 %. Graphite products such as blocks, rods and crucibles are produced to industrial specifications of 99.9 % carbon purity and dimensional tolerances suitable for high‑temperature applications.

Trade and Export Information - WTZ Gmbh

Germany’s metal and mineral export sector commonly ships to the European Union, the Middle East, North Africa and East Asian markets, where automotive, construction, appliance and infrastructure projects drive demand. Bulk commodities like coke, coal and graphite are typically loaded in 20‑ft or 40‑ft containers or in bulk vessels, with standard Incoterms such as FOB Hamburg or CIF Shanghai. Buyers usually request compliance with EU REACH regulations, ISO 9001 quality management certification and, where applicable, CE marking for metal products. Third‑party inspection agencies (e.g., SGS, Bureau Veritas) often perform pre‑shipment sampling and laboratory analysis to verify purity, moisture and elemental composition. Shipping documentation normally includes a commercial invoice, packing list, certificate of origin and material safety data sheet for chemical products.

Sourcing from WTZ Gmbh - Buyer Guidance

When sourcing from WTZ Gmbh, buyers should request a recent material test report that confirms purity, chemical composition and moisture content for each product batch. For aluminum ingots and copper scrap, a mill test certificate showing alloy composition and dimensional tolerances is standard. Fertilizer purchases normally require a fertilizer analysis certificate indicating N‑P‑K percentages and a safety data sheet that meets REACH requirements. Coke and carbon products should be accompanied by an analysis of calorific value, ash and sulfur content. Samples are typically provided in 1 kg quantities for metals and 5 kg for chemical powders, with lead times of 2‑4 weeks depending on production scheduling.

What are the typical purity levels for the aluminum ingots offered by WTZ Gmbh?

Aluminum ingots are generally supplied with a purity of 99.5 % to 99.9 % aluminum, meeting standard alloy specifications for extrusion and rolling.

Which grade of copper scrap is listed in the catalogue?

The catalogue lists copper scrap without a specific grade, so buyers should request the copper content percentage, which is commonly around 99 % for high‑grade scrap.

What nitrogen content does the urea product contain?

The urea product is specified as 46 % nitrogen, which is the typical standard grade used for agricultural fertiliser applications.

How are the NPK fertilizers formulated?

Two formulations are listed: NPK 15‑15‑17 and NPK 20‑20‑20, indicating the percentage by weight of nitrogen, phosphorus (as P₂O₅) and potassium (as K₂O) respectively.

What form and typical specifications are the graphite products supplied in?

Graphite is offered as blocks, rods and crucibles, usually with a carbon purity of 99.9 % and dimensions that conform to industrial furnace and electrode standards.

Which certifications should a buyer verify before purchasing coke or carbon products?

Buyers should verify REACH compliance, request an ISO 9001 quality certificate and obtain a third‑party analysis of calorific value, ash and sulfur content for coke and carbon materials.

What packaging options are available for the silicon carbide powder?

Silicon carbide is typically packed in moisture‑proof multi‑layer bags of 25 kg or in bulk containers, with labeling that includes particle size distribution and purity grade.

What is the usual lead time for a full container load of metallurgical coke?

Lead times for a full 40‑ft container of metallurgical coke are generally 2 to 4 weeks after order confirmation, subject to production scheduling and shipping arrangements.
