Guruch tasma
Mahsulot taqdimoti
Quyma, issiq prokat, sovuq prokat, issiqlik bilan ishlov berish, sirtni tozalash, kesish, pardozlash va keyin qadoqlash orqali elektrolitik mis, rux va mikroelementlarga asoslangan guruch plitalari xom ashyo sifatida. Materiallar ishlash, plastiklik, mexanik xususiyatlar, korroziyaga chidamlilik, ishlash va yaxshi qalayni qayta ishlaydi. U elektrotexnika, avtomobilsozlik, aloqa, apparatura, bezatish va boshqa sohalarda keng qo'llanilgan.
