Why Did Apple Stop Using Titanium for MacBooks?

Are you wondering why your new iPhone has a titanium frame, but your MacBook1 is still made of aluminum? This isn’t an oversight. Apple made a very deliberate manufacturing choice. Apple stopped using titanium for MacBooks primarily due to its high cost and extreme difficulty in machining at scale. Aluminum provides a much better balance […]

Does titanium turn green?

Worried your titanium parts will discolor? Cheaper metals often turn green, causing costly failures. Real titanium’s properties prevent this, ensuring long-term stability and a professional look. No, pure titanium does not turn green. A stable, self-healing oxide layer1 forms on its surface, protecting it from reacting with elements like water or air. This strong barrier […]

Is metal fabrication different from steel milling?

Are you confused by terms like fabrication and milling? This confusion can lead to project mistakes and ordering the wrong materials. Let’s clarify these key manufacturing processes for you. Metal fabrication is a broad process of building metal structures through cutting, forming, and joining. In contrast, steel milling is a specific machining process that uses […]

Is a titanium exhaust better than stainless steel?

Struggling to pick between titanium and stainless steel for an exhaust? A wrong move could add weight and compromise performance, hurting your bottom line. I’ll help you decide. Yes, a titanium exhaust is often better for pure performance. It cuts weight significantly and resists heat extremely well. However, stainless steel provides excellent durability and corrosion […]

Why does titanium need to be welded under a vacuum?

Welding titanium seems straightforward, but failed welds cost time and money. The material cracks, projects stall, and you’re left wondering what went wrong. The secret is the environment. Titanium must be welded in a vacuum or under a protective inert gas shield. This is because at high temperatures, titanium reacts aggressively with oxygen and nitrogen […]

Is Titanium Cookware Really Non-Stick?

Are you tired of pans that stick or scratch easily? You want healthy, durable cookware, but the choices are confusing. Titanium cookware seems like a great solution, but does it work? Yes, titanium cookware1 can be exceptionally non-stick when used correctly. Pure titanium pans require preheating and sometimes seasoning to prevent sticking, but their durability […]

Why are aluminium and titanium used on airplanes?

Finding the right aerospace material is tough. A wrong choice compromises safety and budget. Understanding aluminum and titanium’s roles gives you the confidence to select the best option. Airplanes are built using both aluminum and titanium for specific reasons. Aluminum makes up the bulk of the airframe because it’s lightweight and easy to shape. Titanium […]

Is pure titanium soft?

Struggling to understand titanium’s real properties? You hear it’s incredibly strong, but then someone calls it soft. This confusion can lead to expensive mistakes when choosing materials for your project. Yes, commercially pure titanium is relatively soft when compared to most steel alloys. Its hardness is similar to annealed stainless steel but much harder than […]

How does an air heat exchanger work?

Worried about wasted heat and high energy bills in your plant? This lost energy hurts your bottom line. An air heat exchanger captures and reuses that heat effectively. An air heat exchanger transfers heat from one air stream to another without mixing them. Hot exhaust air passes over metal plates or tubes, warming them. Cooler […]

What is rolling and what are the types of rolling process in metal working?

Finding the right metal finish is tough. Choosing the wrong rolling process causes delays and impacts quality. I will explain the key types to help you source confidently. Metal rolling reduces a metal’s thickness by passing it through rollers. Key types are hot, cold, cross, and profile rolling. Each method achieves different properties, tolerances, and […]

Is Titanium Grade 7 (UNS R52400) The Right Choice For Your Project?

Worried about equipment failing from severe corrosion? These failures are costly and halt operations. Grade 7 titanium1 offers superior protection where other metals simply dissolve. Yes, if your project involves harsh acidic or chloride environments. Grade 7 titanium (UNS R52400) is a commercially pure grade alloyed with palladium2. This addition makes it the most corrosion-resistant […]

What are the Apple products built with titanium alloy?

Struggling to track which Apple products use titanium? This confusion affects your choices, whether you’re buying or designing. Here’s the clear list you need for confident decision-making. Apple uses titanium alloy in its premium devices, including the iPhone 15 Pro and Pro Max, the Apple Watch Ultra, and historically, the PowerBook G4. This choice enhances […]
