Paib lub zog: Tsawg kawg ntawm 50 KSI (345 MPA). Qhov no siab tawm lub zog tso cai rau cov hlau kom withstand cov load tseem ceeb uas tsis muaj kev cuam tshuam loj, ua rau haum rau cov khoom siv thauj khoom.
Lub zog tensile: Yam tsawg kawg nkaus ntawm 65 KSI (450 mpa). Lub zog tensile kom ntseeg tau tias cov hlau tuaj yeem tswj cov khoom siv heev thiab tiv thaiv tawg hauv kev ntxhov siab.
Elongation: Yam tsawg kawg nkaus ntawm 21% hauv 2 nti (50 hli) thiab 18% hauv 8 ntiv tes (200 hli). Qhov elongation qhia tias tus qauv hlau ua qauv, tso cai rau nws kom deform ntau ua ntej poob qis. Cov cuab yeej no yog qhov tseem ceeb rau kev nqus lub zog thaum cuam tshuam thiab tiv thaiv kev ua kom tsis txhob ua haujlwm tam sim ntawd.
