WHAKAMĀRAMA:
Ko te hikohiko COBALTHARD 1FC te koranu paerewa pakeke rawa atu i roto i te rōpū koranu cobalt e whakamahia ana mō te kakahu whakakoi pāmahana teitei e pā ana ki te waikura. He nui te nui o ngā warowaiha chromium i roto i ngā putunga o tēnei koranu e pā ana ki te ātete kakahu whakakoi tino pai. Mā te tāpiri o te tungsten ka whakarei ake i te pakeke pāmahana teitei me te pakari o te matrix mō te ātete kakahu piripiri me te matūriki totoka. Ka pai te piri ki ngā maitai katoa, tae atu ki te kowiri tira.
NGĀ TONO:
Te mata mārō o ngā pane takirere, ngā mowhiti hiri o te papu pēhanga teitei me ngā wāhanga o ngā kuru.
TE PAKARIKI O TE PARURU O TE MEA WHAKAPĀ: 50 – 56 HRC (520- 620 Hv)
TE HANGANGA MATUA NOA O TE MEA WHAKAPĀ (%):
| C | Si | Mn | Cr | W | Co |
| 2.15 | 0.47 | 1.03 | 31.25 | 12.72 | Para |
TŪRANGA WHAKAPĀ: PAPA, POUTŪ KI RUNGA, KI RUNGA
NGĀ RAHI E WĀTEA ANA ME NGĀ AUAU E TAUTOKO ANA (DC +):
| Rahi (diameter mm) | 3.2 | 4.0 | 5.0 |
| Roa (mm) | 350 | 350 | 350 |
| Awhe o Ia Wā (Amp) | 90 – 120 | 110 – 150 | 140 – 180 |
NGĀ TUHIPOKA MŌ TE WHAKAMAHINGA:
Whakamahanahia ki te 300ºC, neke atu rānei i te nuinga o te wā.
Whakamahia ngā rākau tohu pāmahana PHILARC, te ine pāmahana ā-waenga rānei a PHILARC hei whakatau mēnā kua eke te pāmahana tika ki te taumata tika i mua i te whakarewa.
He whai hua te whakamahana i muri i te whakarewanga i te 600ºC, me te whakaroa i te whakamatao i muri i te whakarewanga hei ārai i te pakaru.
Whakamarokehia ngā irahiko i te 150-200ºC mō te 30 – 60 meneti i mua i te whakamahinga. Whakamahia ngā oumu whakamaroke kawe a PHILARC.
