Mechanical matut mahkai lam ni hta ahkyak ai arung arai ni hku nna, fasteners ni a bungli galaw ai lam gaw lang ai arung arai ni hta grai madung nga ai. N bung ai arung arai ni hte galaw ai fastener ni gaw, shanhte a n-gun, n-gun n rawng ai, n-gun n rawng ai, manu jahpu ni nga ai majaw, bungli galaw ai shara amyu myu hta jai lang mai ai.
Carbon steel gaw manu n law ai, n-gun kaba ai, galaw na matu loi ai majaw, n-gang ni hpe shinggrup na matu grau nna lang ai. Low-carbon n-gang (C1010 zawn re ai) hpe gaw, n-gun n rawng ai n-gang hte n-gang ni a matu lang ai rai nna, n-gun n rawng ai n-gang hpe n-gun rawng ai (sh) wan n-gun hte n-gun rawng ai hku n-gun rawng ai hku n-gun rawng ai hku n-gun rawng ai. Medium-carbon steel (C1045 zawn re ai) gaw n-gun grau ja ai hpe lu la nna, n-gun hpe shayawm kau ngut ai hpang, jak rung npawt nhpang daw ni a matu mung htuk manu ai. High-carbon steel hpe grau n-gun ja ra ai laksan bungli ni hta lang ai, raitim, n-gun n law ai hpe madun dan ai.
Chromium, molybdenum, nickel zawn re ai n-gun dat ni hpe jat bang ai majaw grau kaja wa ai Alloy steel hpe n-gun kaba hte n-gun yawm ai lam hpe hkam sharang ra ai, mawdaw hte nbungli zawn re ai bungli ni hta grai lang ma ai. Ga shadawn, 40Cr steel hpe, n-gun shayawm nna, n-gun shayawm ngut ai hpang, grai kaja ai n-gun hte n-gun shayawm lu ai atsam hpe madun dan nna, engine hte jak kaba ni a matu gyit da ai arai ni hta law law lang lang lang ai.
Stainless steel gaw n-gun n rawng ai majaw mying kaba ai rai nna, madung hku nna masum hku garan ginhka da ai: austenitic (304 hte 316 zawn re ai ni), martensitic, hte ferritic. 304 n-gun n rawng ai n-gang gaw grai kaja ai n-gun n rawng ai hte n-gun n rawng ai n-gun rawng ai majaw, malu masha hte tsi mawan hpaga lam ni hta grai lang ma ai. molybdenum, chloride n-gun hpe ninghkap lu ai atsam hpe jaw ya nna, panglai hta lang na matu htuk manu ai grup yin ni hpe n-gun jaw ai. Martensitic stainless steel (410 zawn re ai) gaw n-gun hte n-gun n-gun hpe rap ra hkra jaw ya nna, htu ai arung arai ni hte bearing ni hpe gyit da ai arung arai ni hta lang ai.
Aluminium, magri, titanium zawn re ai n-re-hpyen n-gang ni hta mung, laksan jai lang ai lam ni nga ai. Aluminum alloy fasteners ni gaw n-gun n law ai, n-gun n rawng ai, n-gun grai ja ai majaw nbungli hte electronic jak ni hta jai lang mai ai. Copper alloys (brass zawn re ai) ni gaw grai kaja ai n-gun hte n-gun n-gun hpe ninghkap lu ai majaw, wan n-gun matut mahkai ai lam ni hta law law lang lang lang ai. Titanium alloy fasteners ni gaw n-gun kaba ai, n-gun ja ai-n-gun ja ai, n-gun ja ai hpe hkam sharang lu ai, raitim manu dan ai hte madung hku nna nbungli hte high-end tsi mawan ni hta jai lang ai.
Tsun ga nga yang, fastener arung arai ni hpe lata ai shaloi, bungli amyu myu a ra kadawn ai lam ni hpe hkap la lu na matu, jak rung atsam, grup yin hte htuk manu ai lam, manu jahpu-htuk manu ai lam ni hpe atsawm sha myit yu ra ai.
