Akasin haka, samfurin CT6 yana riƙe da ƙimar fashewar Class C, rufe buƙatun BT4 kuma ana amfani da shi zuwa yankuna masu haɗari masu haɗari kamar hydrogen da acetylene. T6 kayan aiki dole ne su kula da yanayin zafi sama da 85 ° C.

Cikin sharuddan zafin jiki rukunoni, T6 yana wakiltar mafi girman matakin aminci, yana nuna cewa ƙananan zafin jiki na kayan aiki ya fi dacewa.

Saboda, CT6 yana da ingantaccen rarrabuwa-hujja.
