Guruch tasma
Mahsulot bilan tanishtirish
Elektrolitik mis, rux va mikroelementlarni xom ashyo sifatida ishlatish orqali quyma, issiq prokat, sovuq prokat, issiqlik bilan ishlov berish, sirtni tozalash, kesish, pardozlash va keyin qadoqlash orqali amalga oshiriladi. Materiallar ishlash, plastiklik, mexanik xususiyatlar, korroziyaga chidamlilik, ishlash va yaxshi qalay jarayonlarini amalga oshiradi. U elektrotexnika, avtomobilsozlik, aloqa, apparat, bezatish va boshqa sohalarda keng qo'llanilgan.
