Chidimbu chemhangura cheLead Frame

Mutsetse wemhangura weFuremu yeLead Mufananidzo Wakaratidzwa

Tsananguro pfupi:

Zvinhu zvemufuremu we lead zvinogara zvichigadzirwa ne alloy yemhangura, Iron ne phosphorus, kana mhangura, nickel ne silicon, izvo zvine alloy yakajairika Nhamba ye C192(KFC), C194 ne C7025. Alloys idzi dzine simba guru uye dzinoshanda zvakanaka.

Nhanganyaya yeChigadzirwa

Zvinhu zvefuremu yemutobvu zvinogara zvakagadzirwa nemhangura, Iron nephosphorus, kana mhangura, nickel nesilicon, izvo zvine nhamba yearuni yakajairika yeC192(KFC), C194 neC7025. Aya maruni ane simba guru uye mashandiro. C194 uye KFC inonyanya kumiririrwa nemhangura, iron nephosphorus alloy, ndizvo zvinonyanya kushandiswa muruni.

C7025 imhando yemhangura nephosphorus, silicon. Ine simba rekupisa rakawanda uye inochinjika zvakanyanya, uye haidi kurapwa nekupisa, zvakare iri nyore kudhindwa. Ine simba rakawanda, hunhu hwakanaka hwekupisa, uye yakakodzera mafuremu emota, kunyanya pakuungana kwemasekete akabatanidzwa ane density yakakura.
