Birta guga EN45
EN45 waa birta guga manganese. Yacni, waa bir kaarboon ku badan tahay, raadadka manganese-ka oo saameeya hantida birta, iyo in guud ahaan loo isticmaalo ilo-biyoodyo (sida ilaha ganaaxa ee baabuurta duugga ah). Waxay ku habboon tahay adkaynta saliidda iyo xanaaqa. Marka lagu isticmaalo saliidda qallafsanaanta iyo xaalada xanaaqsan EN45 waxay bixisaa sifooyin guga oo heer sare ah. EN45 waxaa caadi ahaan loogu isticmaalaa warshadaha baabuurta soo saarista iyo dayactirka ilaha caleenta.
Birta guga EN47
EN47 waxay ku habboon tahay adkaynta saliidda iyo heerkulka. Marka lagu isticmaalo saliidda qallafsanaanta iyo xaalada xanaaqsan EN47 birta guga waxay isku daraysaa sifooyinka guga oo leh xidhid wanaagsan iyo iska caabin xoqan. Marka la adkeeyo EN47 waxay bixisaa adkeysi aad u fiican iyo iska caabin naxdin leh taas oo ka dhigaysa birta guga guga ee ku habboon qaybo ka mid ah walaaca, shoogga, iyo gariirka.EN47 waxaa si weyn loogu isticmaalaa warshadaha gawaarida iyo codsiyo badan oo injineernimada guud ah. Ku haboon codsiyada u baahan xoog xoog badan oo adag. Codsiyada caadiga ah waxaa ka mid ah gacan-qabsiga, jilbaha isteerinka, gears, spindles, iyo bambooyin.
