Titanium Element For Mobile Phones Domestic And Abroad

The following is the information of some mobile phone models and titanium alloy grades selected from titanium alloys domestic and abroad:

1. Domestic Brands

1) Huawei Mate 70 Series

-Application Part: high-gloss titanium middle frame (basalt structure)

-Grade Speculation:

-Titanium-Aluminum composite materials are used (combining titanium and aluminum by hot isostatic pressing technology).

-It involves TA1/TA2 pure titanium or TC series titanium alloys, which are treated by special processes to improve hardness and gloss.

-Features: The gloss is 3.5 times higher than that of matte titanium, the wear resistance and drop resistance are significantly enhanced, and the mass production of high-gloss titanium middle frame is realized for the first time.-Picture reference: Huawei Mate 70 Pro+ Highlight titanium mid-frame award.

2) OPPO Find N5

-Application Parts: Titanium alloy sky dome hinge (3D printing)

-Grade speculation:

-Using TC4 titanium alloy (Ti-6Al-4V), manufactured by 3D metal printing technology, the thickness is only 0.15mm.

-Features: The thickness of the hinge is reduced by 26%, the drop resistance is increased by 100%, and it has passed the certification of non-inductive creases in Rheinland, Germany.

3) Xiaomi 14 Pro Titanium Special Edition

-Application Part: middle frame

-Grade: TA-2 pure titanium (99% purity)

-Features: The surface is treated with brushed texture + nano-coating, anti-fingerprint and wear-resistant, and the middle frame is composite with high-strength aluminum alloy to enhance the structural strength.

2. International Brands

1) Apple iPhone 15 Pro series

-Application parts: middle frame and body

-Grade speculation:

-Ti-6Al-4V titanium alloy (TC4) or Ti-6Al-7Nb medical grade titanium alloy is used, the specific composition is not disclosed.

-Features: The world's first all-titanium middle-frame mobile phone, the weight is about 10% lighter than stainless steel, the hardness is improved, and the design without incision is supported.

2) Samsung Galaxy S24 Ultra

-Application part: Titanium alloy frame

-Grade speculation: Not clearly disclosed, it may be a high-strength titanium alloy such as Ti-6Al-4V or Ti-10V-2Fe-3Al.

-Features: For the first time, titanium alloy is used in the Android flagship to improve scratch resistance and the weight is similar to the previous generation (232g).

3. Other Brands

-Glory Magic Vs2: Luban titanium hinge is used, the specific grade is not disclosed, and it is combined with aerospace-grade rare earth magnesium alloy to improve strength.

-Essential Phone PH-1 (2017): An early model with a pure titanium middle frame, the grade is Grade 5 titanium alloy (TC4).

4. Summary and Precautions

1) Grade Transparency: Most manufacturers have not fully disclosed the specific composition of titanium alloys, and some of the information is based on industry speculation.

2) Process Differences:

-Huawei and Apple use traditional titanium alloy processing (such as CNC and polishing)；

-OPPO and Xiaomi try 3D printing or pure titanium composite technology.
