4J42 Tsvimbo Inodzorwa Nekuwedzera Alloy Bar Fe Ni Precision Alloy Material Mufananidzo Wakaratidzwa

4J42 Tsvimbo Inodzorwa Kuwedzera Alloy Bar Fe Ni Precision Alloy Material

Tsananguro pfupi:

Tsananguro yeChigadzirwa

Rodhi ye4J42 alloy isimbi inodzorwa neFe-Ni ine nickel inosvika 42%. Ine thermal expansion coefficient yakafanana negirazi rakaoma neceramics, zvichiita kuti ive yakakodzera kushandiswa kwekuvhara girazi kubva kusimbi kuenda kusimbi uye ceramic kubva kusimbi kuenda kusimbi.

Chigadzirwa ichi chinopa kushanda kwakasimba kwekuwedzera, hunhu hwakanaka hwekugadzirisa, uye kuvimbika kwakanaka kwekuvharisa, chinoshandiswa zvakanyanya mukupakata kwemagetsi, zvishandiso zve vacuum, uye zvikamu zvemuchadenga.

Kuwanda:8.1 g/cm³

Kuwedzera kwekupisa (20–300°C):5.3 ×10⁻⁶/°C

Simba reKusimba:450 MPa

Kuoma:HB 130–160

Kushanda Kwekupisa:60°C kusvika 400°C

Mutsetse:GB/T, ASTM, IEC

Fe-Ni inodzora kuwedzera chiwanikwa
Chiyero chekuwedzera kwekupisa chakagadzikana
Kushanda zvakanaka kwazvo kwekuvhara girazi/ceramic
Kugona kushanda zvakanaka uye kuchinjika
Inopihwa mumatanda, waya, mitsetse, uye mafomu akagadzirirwa
