Yog tooj liab-nickel muaj zog

{{0 {}} puas tooj liab-npib muaj zog?

Copper-nickel alloys (like Cupronickel) have moderate strength compared to pure metals but are generally less strong than high-strength steels or titanium. Their tensile strength typically ranges from 300–700 MPa (depending on the specific alloy and heat treatment), which is higher than pure copper (≈220 MPa) but lower than structural steels (often >450 MPa for carbon steel, or >800 MPa rau cov hlau stainless) .

4. Yuav ua li cas qhia yog tias muaj qee yam tooj liab?

Siv cov hau kev no los txheeb xyuas cov tooj liab lossis tooj liab alloys:

Qhov muag pom thiab lub cev kev sim:
