6J13 Manganin Alloy Strip

Nchịkọta Ngwaahịa

6J13 eriri manganin alloy, ngwaahịa alloy na-eguzogide oke nkenke nke Tankii Alloy Material mepụtara ma mepụta n'onwe ya, bụ alloy na-eguzogide nkenke nke dabere na ọla kọpa-manganese-nickel (Cu-Mn-Ni). Ejiri usoro ịgbaze oghere dị elu, mpịakọta oyi na-agafe agafe, na usoro annealing ikuku na-achịkwa, eriri a na-enweta oke nha siri ike na njirimara eletriki na-agbanwe agbanwe. Ọ na-ejikọta uru ndị bụ isi nke alloy manganin:ike siri ike dị elu, obere ihe na-eguzogide okpomọkụ (TCR), naezigbo nguzogide nchara—na-eme ka ọ bụrụ ihe a kacha mma maka ihe mgbochi siri ike, shunt current ziri ezi, na ihe ndị e ji atụ eletriki na ngwa ọrụ mmepụta ihe, ngwa eletrọniki ụgbọala, na ngalaba ngwa nkenke.

Uru Ndị Dị Mkpa (vs. Alloys Ndị Na-eguzogide Azụ)

Mpempe manganin 6J13 pụtara ìhè maka arụmọrụ ya na nhazi ya nke ọma:

A na-ejigide iguzogide nrụgide nke ọma na 0.44±0.04 μΩ·m (20℃), nkezi oke okpomọkụ iguzogide nrụgide (TCR) sitere na -20×10⁻⁶/℃ ruo +20×10⁻⁶/℃ n'ime -50℃ ruo 150℃, nke dị ala karịa nke constantan (6J40: ±40×10⁻⁶/℃). Mgbe awa 1000 nke ọrụ gasịrị na 120℃, mmụba iguzogide nrụgide erughị 0.01%, na-eme ka nha nha ogologo oge ziri ezi nke ngwa ziri ezi.

Nhazi otu alloy ahụ (nha ọka ≤25μm) na-eme ka ọrụ ya dị mma nke ukwuu. N'ọkara ike, ike nrụgide ya ruru 550-650 MPa, ogologo ya dịkwa 15-20%, nke nwere ike iguzogide stampụ na mgbagọ dị elu (opekempe radius mgbagọ ≥2× ọkpụrụkpụ) na-enweghị mgbawa. Elu a na-egbuke egbuke (Ra ≤0.2μm) dabara adaba maka ịcha kemịkalụ dị oke mma, yana opekempe obosara ahịrị e sere nke 0.03mm.

Sistemụ alloy Cu-Mn-Ni na-emepụta ihe nkiri dị oke egwu, nke nwere ike iguzogide nchara ikuku, mmiri dị ọcha, na gburugburu kemịkalụ dị nro (pH 4-10). Ọ na-agafe ule mmiri ASTM B117 nke awa 1000 na-enweghị nchara doro anya. Ka ọ dị ugbu a, ọ nwere obere ike thermoelectric (≤2μV/℃ vs. copper), na-ebelata nnyonye anya nha na sekit voltaji dị ala.

Ma e jiri ya tụnyere 6J12 manganin alloy (resistvion 0.47±0.03 μΩ·m), 6J13 nwere ntakịrị iguzogide dị ala mana ọ kwụsiri ike na nhazi ogbe yana obere ọnụ ahịa mmepụta. Ọ bụ nhọrọ dị ọnụ ala maka ihe ndị na-eguzogide nhazi ziri ezi site na etiti ruo elu, na-ahazi arụmọrụ na akụ na ụba.
