Scrap bechte waqt sabse zaroori hai ye pehchaanna ki aapke paas kaunsa metal hai. Teen sabse common metal copper, aluminium aur iron hain.
Copper (taamba)
Laal-bhoore rang ka hota hai aur bhaari hota hai. Iska rate sabse zyada hota hai. Magnet isse nahi chipakta. Wire, pipe aur AC/fridge ke coil me milta hai.
Aluminium
Chaandi jaisa chamakdaar aur bahut halka hota hai. Magnet nahi chipakta. Window frame, bartan aur cooler ke parts me milta hai. Rate copper se kam aur iron se zyada hota hai.
Iron (loha)
Kaala ya bhoora, bhaari aur magnet se chipakne wala hota hai. Rate sabse kam hota hai, lekin bulk me kaafi paisa ban jata hai.
Ek aasan test
Magnet lekar dekhein. Agar chipakta hai to iron hai. Nahi chipakta aur laal rang ka hai to copper, aur chamakdaar halka hai to aluminium.
