Balaadhinta Hoose ee Alloy Kovar 4j29 silig, 29HK silig loogu talagalay daawaha xidhidhiyaha galaas
Alloy-4J29 ma aha oo kaliya balaadhinta kulaylka oo la mid ah muraayadda, laakiin qalooca fidinta kulaylka aan tooska ahayn ayaa badanaa la samayn karaa si ay ugu dhigmaan muraayadda, taas oo u oggolaanaysa wadajirku inay u dulqaadan karaan heerkul ballaadhan. Kiimiko ahaan, waxay ku xidhaa galaas iyada oo loo marayo lakabka oksaydhka dhexe ee nikkel oxide iyo kobalt oxide; saamiga birta oksaydhku waa yar yahay sababtoo ah hoos u dhigida kobalt. Xoogga dammaanadda waxay aad ugu tiirsan tahay dhumucda lakabka oksaydhka iyo dabeecadda. Joogitaanka kobaltku wuxuu ka dhigayaa lakabka oksaydhku inuu si fudud u dhalaali karo oo ku milmi karo muraayadda dhalaalaysa. Midabka cawl, cawl-buluug ama cawl-brown ayaa tilmaamaya shaabad wanaagsan. Midabka macdanku waxa uu tilmaamayaa oksaydh la'aan, halka midabka madaw uu tilmaamayo birta oksaydhaysan ee xad dhaafka ah, labada xaaladoodba waxa ay keenayaan kalagoys daciif ah.
Codsiga:Inta badan loo isticmaalo qaybaha faakuumka korontada iyo xakamaynta qiiqa, tuubada shoogga, tuubada shidda, magnetron galaas, transistor-ka, fur shaabada, gudbinta, wareegyada isku dhafan ee rasaasta, chassis, biraha iyo xidhitaanka guryaha kale.
