How we identify and group the different grades — from steel to tungsten carbide.
Below we describe the grades we accept, along with their purity requirements. Classification determines the price — if you're not sure which group your material falls into, we'll assess it on site or from a photo.
Up to 3–4 mm thick: sheet, pipe, profiles. Impurities from 3% under the PN-85/H-15000 standard.
Furnace and non-furnace grade. Impurities from 2% under the PN-85/H-15000 standard.
Furnace and non-furnace grade. Impurities from 1% under the PN-85/H-15000 standard.
Furnace and non-furnace grade: pipes, radiators, castings, housings. Impurities from 2% under the PN-85/H-15000 standard.
A selected cast-iron grade: car brake discs and drums, sent to the automotive industry.
99.9% copper content. Wire over 1 mm thick, bright, free of tinning, paint and contaminants.
At least 99% copper. Stranded wire, sheet, tube, castings — free of lacquer, insulation, solder and contaminants.
At least 98% copper. Over 1 mm thick: sheet, wire, castings. Trace contaminants allowed.
At least 98% copper. Up to 2% iron (Fe) contamination allowed.
At least 95% copper. Trace metallic contaminants, lacquer, enamel and insulation allowed up to 5% in total.
A zinc-copper alloy with at least 58% copper: valves, sheet, tube, castings. Free of contaminants.
Castings, vessels, bathroom fittings, valves. A coating of another metal, solder and trace Fe allowed.
A copper alloy with other metals, at least 82% copper: castings, bushings, bearings.
Swarf from machining. Up to 2% contamination by another metal allowed.
Other aluminium alloys without grade separation, up to 2% contaminants. No castings, blinds, shutters or foil.
Thin foil and flexible ventilation ducting — a grade with a low recovery rate.
Window blinds, free of iron and cords — a grade with a low recovery rate.
Shutters from gates and security doors. Foam contamination allowed, no Fe.
Cast aluminium alloys. Grease and Fe contamination allowed up to 2%.
Car alloy wheels — without valves, sleeves or balance weights.
Free of plastic contamination, no fluid. Up to 2% Fe contamination allowed.
Aluminium radiators with copper tubing, free of metallic and non-metallic contaminants.
Aluminium beer and drinks cans.
Sheet in the form of printing plates.
Power-line scrap: wires and flat bars, free of grease contamination and braiding.
Extruded aluminium: profiles, angles, sections. No lacquer, welds or contaminants.
As bare profile, but with lacquer or an anodised oxide layer allowed.
Profile with a plastic thermal-break insert.
Grade-sorted sheet, free of metallic and non-metallic contaminants.
Offcuts and waste from the roofing trade, free of tar and Fe contamination.
Castings, brittle — they show a crystalline structure when broken.
A zinc-aluminium alloy heavier than aluminium castings: furniture fittings, handles, fixtures, old valves.
Stainless steel with at least 8% nickel. Non-magnetic or weakly magnetic. Structures, finishes, catering furniture.
Pots, flasks, bowls — 2–4% nickel content.
High-alloy steels for cutting tools: blades, drills, taps. They contain chromium, vanadium and tungsten (sometimes cobalt and molybdenum).
A powder-metallurgy material: turning tools, drills, cutting inserts, hammer tips. We classify both clean carbide and de-brazed parts.
Free of metallic and non-metallic contaminants, in sheet form.
Sheet, remelts, castings. Non-metallic contaminants allowed.
Automotive, UPS, industrial and traction.
Rare cells from aviation, military and specialist equipment.
