Ihambisana Neshubhu Lethusi Le-Tin Phosphor Elijwayelekile
Isingeniso I-tin-phosphorus bronze tube iyithusi eline-tin ne-phosphorus-phosphorus njengezici eziyinhloko ze-alloy, equkethe i-2-8% ye-tin, i-0.1-0.4% ye-phosphorus, kanti enye ithusi, okuyi-alloy yokuqala eyasetshenziswa abantu.Abantu bakuqala basebenzisa le ngxube ukuze bakhiphe izitsha zethusi, ezadlala indima enkulu kwezolimo, izimboni kanye nezempi ngaleso sikhathi.Kusekhona izinto ezisele, okwanele ukubona ukuthi le ngxubevange ...
