High strength and high-alloy structural maraging steel scrap. It is used in production of high pressure equipment, in manufacture of rocket motor casings, heavy-loaded critical parts, aircraft, shafts, casings and other parts, fasteners, gear transmissions of engines for artillery, machine guns and submarines, etc. Chemical composition: Ni 17,7% — 19,00% Cr < 0,1% Cо < 8,5% — 9,5% Mo <4.6% - 5.5% Fe - balance

Scrap of alloys with a given temperature coefficient of casting expansion (TCLE). It is used for vacuum seals of electronic equipment elements with glasses С49-1, С52-1, С48-1, С47-1.

Alloy scrap with high magnetic permeability (soft magnetic alloys). It is used in production of cores for small-sized transformers, chokes and relays operating in weak fields of magnetic shields. Scrap with small thickness (0.05-0.02 mm) is used in production of cores of pulse transformers, magnetic amplifiers and static relays.Chemical composition: Ni 78,5% — 80% Mn 0,6% — 1,1% If 0.3% - 0.5% C < 0.3% Mo 3.8% - 4.1% Fe = balance GOST 10994-74 Precision alloys.

Scrap and waste of heat-resistant chromium-nickel steels with a high content of chromium and nickel

Tungsten has a high density, which makes it convenient for ionizing radiation shielding. Despite the higher density compared to traditional and cheaper lead, tungsten shielding is less heavy with equal shielding properties, and more effective if the weight is the same. Tungsten is a very refractory and hard metal, which makes it difficult to process. Therefore, more ductile tungsten alloys with nickel, iron, copper, etc. are used. Cr 16.0%-18.0% We buy alloys of the following grades: VN/VNZh alloys (category: Tungsten 12) (W - 80 - 90% Ni - 5 - 10% Fe - 1- 3%) VD alloys (W - 70 - 80% Cu - 20 - 30%)
