Ua kaupaonaʻo Alumini e pili ana 2.70 g / cm³, ʻOiaiʻo Titanium 4.51 g / cm³. Pēlāʻo Anuminum i hāʻawi i kahi kūpono nui i nā noi e pili ana i ka hopena o ka hōʻemi nuiʻana he koʻikoʻi.

ʻO ka meaʻoi aku ka ikaika?

I nā hana maʻamau, Ti-6al-4v (Kumu 5 Titanium) hoʻokō i nā ikaika hope loa o nā ikaika 900 Mpa, a kahi kiʻekiʻe a me ka ikaika o ka ikaika ikaika 7075-T6 luna a puni 570 Mpa.

He aha ka mea maikaʻi, alumini a iʻole titanium?

• Aluminum lanakila no ke kaupaona haʻahaʻa, ʻO ka laweʻana / uila, ka maʻalahi o ka machining a me ka welding,
  a me ke kumukūʻai haʻahaʻa-kūpono no ka nui-Volume, nā noi kiko'ī (e.g. nā kino o nā kaʻa, nā mea hana wela).
• Titanium ʻO nā mea maikaʻi loa ma ka ikaika kiʻekiʻe, ʻO ka hōʻehaʻana, a me nā kuleana corrosion-resison, nui loa ma nā wela kiʻekiʻe (a hiki i 400-600 ° C),
  Ke hana nei i nā mea i kohoʻia no Aerospace Engine Engine, nā mea hana uila, a me nā mea kūʻai biomedical.

ʻO Titanium a iʻole Aluminimʻoi aku ka uku?

ʻOi aku ka nui o nā kumukūʻai titinium:

• Mea kūʻai: Ua holoʻo Alumini a hiki i $ 2- $ 3 no kg, Ma kahi o nā mea kūʻai akuʻo Titanium e kūʻai aku ai i $ 15- $ 30 no ke Kg.
• Ka hoʻoiliʻana: Ponoʻo Titanium no ka holoiʻana, Ke kala nei i ke kalaʻana, a me nā undery-metart-squand e hoʻonui hou aku i kāna kumukūʻai 5-10 × ʻO kēlā me kahi mea hoʻohālikelike hoʻohuihui Aluminum.

Ua maʻalahi ka maʻalahi o ka aluminim ma mua o Titanium?

ʻAe. Nā Alloys Annays Alloys (E.g., Ti-6al-4v) hoʻopaʻa inoa inoa a puni 330 HB ma ka pā pōhaku brinell paʻakikī, Aʻo nā mea āpau aluminum maʻamau (6061-T6, 7075-T6) haule ma waena 95-150 hb.

ʻO Titanium kahi paʻakikī kiʻekiʻe a me nā lole i hoʻopaʻaʻia i keʻano o nā alaloa a Aluminum e nānā a nānā paha i lalo o nā kūlana pili like.
