https://www.horbiter.com/en/blancpain-bathyscaphe-grade-23-titanium/Its commercial code is Ti-6Al-4V-ELI or TAV-ELI, where ELI stands for “Extra Low Interstitial”; in an ELI alloy, reduced interstitial oxygen and iron improve ductility and fracture toughness. The Grade 23 titanium is, like for like, more resistant to fatigue loads, wear and corrosion from saltwater and guarantees enhanced resistance to micro-cracks than Grade 5. Thumbs up, Blancpain, for introducing something new and performance-oriented; it adds to the product’s uniqueness.
它的商业代码是Ti-6Al-4V-ELI或TAV-ELI，其中ELI代表 "超低间隙"；在ELI合金中，间隙氧和铁的减少提高了延展性和断裂韧度。与5级钛合金相比，23级钛合金对疲劳负荷、磨损和盐水腐蚀的抵抗力更强，并保证对微裂纹的抵抗力更强。竖起大拇指，宝珀，推出了一些新的和以性能为导向的东西；这增加了产品的独特性。
