The iPhone 16 Pro Max utilizes Grade 5 titanium, also known as Ti-6Al-4V, for its frame. This alloy, composed of 90% titanium, 6% aluminum, and 4% vanadium, is not entirely new to Apple’s lineup—it was also used in the iPhone 15 Pro—but it continues to be a key factor in enhancing durability and reducing weight. Grade 5 titanium is renowned for its exceptional strength-to-weight ratio, making it significantly stronger and lighter than the stainless steel used in earlier iPhone Pro models, such as those prior to the iPhone 15 Pro series. This contributes to a premium, lightweight design that withstands everyday wear and tear.
In addition to the alloy itself, Apple has refined its application in the iPhone 16 Pro Max. The titanium frame is bonded to an internal aluminum structure, optimizing the balance between durability and weight. While the weight of the iPhone 16 Pro Max remains approximately 221 grams, similar to the iPhone 15 Pro Max, the use of Grade 5 titanium ensures the device remains lightweight despite its larger display and advanced features.
A notable enhancement for the iPhone 16 Pro Max is the introduction of a microblasted finish on the titanium frame. This finish gives the device a smooth, matte appearance while improving resistance to fingerprints and scratches, further boosting its durability and aesthetic appeal compared to previous models. Additionally, titanium’s superior heat dissipation properties help manage the device’s temperature during intensive tasks, enhancing overall performance.
In summary, the iPhone 16 Pro Max employs Grade 5 titanium (Ti-6Al-4V) with a new microblasted finish, paired with an internal aluminum frame, to deliver enhanced durability and reduced weight, making it a standout feature of this premium smartphone.
