Ang Spark Test: Paano Malalaman Kung Tunay na Titanium ang Binili Mo
Sa Shopee, Lazada, at TikTok Shop — maraming nagbebenta ng "titanium bolts" sa napakababang presyo. Pero paano mo malalaman kung tunay na titanium ito, o baka coated steel o aluminum lang?
Ang Spark Test — Isang Simpleng Workshop Method
Touch the metal to a grinding wheel: Aluminum produces no sparks, while Titanium produces brilliant, bright white sparks. Quick at dirty na test na ginagamit ng mga metalworkers. Pero tandaan: ito ay para sa rough identification lang at maaaring sirain ang surface finish ng bolt.
Mga Visual Clues Na Dapat Tingnan
- 🔍 Weight: Ang titanium ay "medium weight" — mas magaan kaysa equivalent steel bolt, mas mabigat kaysa aluminum
- 🔍 Magnetism: Ang totoong titanium ay non-magnetic. Kung may magnetic pull, malamang steel ito
- 🔍 Surface texture: Ang totoong titanium ay may distinct na matte o satin finish
Red Flags Na Dapat Iwasan
- 🚩 Presyo na masyadong mababa kumpara sa market rate ng genuine titanium
- 🚩 Walang grade specification ("titanium bolt" lang, walang GR5 o Ti-6Al-4V)
- 🚩 Magnetic ang bolt kapag tested
- 🚩 Walang consistent na weight
Ang Mas Reliable na Paraan: Certification
Ang legitimate na titanium bolt manufacturers ay dapat may material certificate na nagsasabing "Ti-6Al-4V" o "GR5" specifically, kasama ang ASTM o AMS specification number. Sa 777 Motoparts, ang lahat ng aming bolts ay certified GR5 (Ti-6Al-4V). Walang guessing game.
