ʻĀpana Alloy Manganin 6J13

ʻIke Huahana

ʻĀpana hao manganin 6J13, he huahana metala kū'ē ki'eki'e i ho'omohala kū'oko'a a hana 'ia e Tankii Alloy Material, he metala kū'ē pololei ma'amau ia e pili ana i ke keleawe-manganese-nickel (Cu-Mn-Ni). Hana 'ia ma o ka ho'ohehe'e 'ana i ka vacuum holomua, ka 'ōwili anuanu multi-pass, a me nā ka'ina hana ho'ohehe'e lewa i kāohi 'ia, ho'okō kēia kaha i nā ho'omanawanui dimensional pa'a loa a me nā waiwai uila kūlike. Ho'ohui ia i nā pono ko'iko'i o nā metala manganin:kūpaʻa kiʻekiʻe resistivity, ka helu mahana kū'ē haʻahaʻa (TCR), a mekūpaʻa maikaʻi loa i ka palaho—e hoʻolilo ana ia i mea makemake ʻia no nā pale kūpaʻa kiʻekiʻe, nā shunt o ke au pololei, a me nā ʻāpana ana uila i nā mea hana ʻoihana, nā mea uila kaʻa, a me nā kahua lako pololei.

Nā Hoʻonohonoho Maʻamau a me ke Kumu Mea

Nā Pōmaikaʻi Koʻikoʻi (vs. Nā Alloys Palekana Maʻamau)

ʻOi aku ka maikaʻi o ke kaha manganin 6J13 no kāna hana kaulike a me ka hiki ke hana:

Mālama paʻa ʻia ke kū'ē ʻana ma 0.44±0.04 μΩ·m (20℃), a ʻo ke ana wela kū'ē awelika (TCR) mai -20×10⁻⁶/℃ a i +20×10⁻⁶/℃ i loko o -50℃ a i 150℃, ʻoi aku ka haʻahaʻa ma mua o ko constantan (6J40: ±40×10⁻⁶/℃). Ma hope o 1000 hola o ka hana ma 120℃, ʻoi aku ka emi o ke kū'ē ʻana ma mua o 0.01%, e hōʻoiaʻiʻo ana i ka pololei o ke ana ʻana i ka wā lōʻihi o nā mea hana pololei.

ʻO ke ʻano like o ka microstructure o ka alloy (ka nui o ka palaoa ≤25μm) e hiki ai ke hana anu maikaʻi loa. I ka wā o ka hapalua paʻakikī, hiki i kona ikaika tensile i 550-650 MPa, a ʻo ka elongation he 15-20%, hiki ke kū i ke kaha kiʻekiʻe a me ke kūlou ʻana (ka radius kūlou liʻiliʻi ≥2 × ka mānoanoa) me ka ʻole o ka haki ʻana. ʻO ka ʻili annealed mālamalama (Ra ≤0.2μm) he kūpono ia no ke kālai kemika ultra-fine, me ka laulā laina etched liʻiliʻi o 0.03mm.

Hoʻokumu ka ʻōnaehana hui Cu-Mn-Ni i kahi ʻili ʻili paʻa, hiki ke kūʻē i ka palaho lewa, ka wai maʻemaʻe, a me nā wahi kemika akahai (pH 4-10). Ua hala ia i ka hoʻāʻo ʻana i ka paʻakai ASTM B117 1000-hola me ka ʻole o ka palaho ʻike ʻia. I kēia manawa, he haʻahaʻa kona hiki ke hoʻohana ʻia i ka thermoelectric (≤2μV/℃ vs. keleawe), e hōʻemi pono ana i ke komo ʻana o ke ana ʻana i nā kaapuni haʻahaʻa voltage.

Ke hoʻohālikelike ʻia me ka 6J12 manganin alloy (resistivity 0.47±0.03 μΩ·m), ʻoi aku ka haʻahaʻa o ka resistivity o 6J13 akā ʻoi aku ka paʻa o ka batch consistency a me ke kumukūʻai hana haʻahaʻa. He koho kūpono ia no nā ʻāpana pale kūpaʻa waena a kiʻekiʻe, e kaulike ana i ka hana a me ka hoʻokele waiwai.
