Grade 1 and 2 titanium powder It is one of the commercially pure titanium grades, also known as CP titanium. Both materials combine low density with good corrosion resistance and, depending on the powder specification, are suitable for additive manufacturing as well as other powder metallurgical processes.
One of the differences between the two grades lies in the permissible oxygen and iron content, which influence their mechanical properties. NMD Metalpowders can help you select the right Titanium powders to meet your component and process requirements.
A comparison of Grade 1 and Grade 2 titanium
Grade 1: High ductility and formability
Grade 1 titanium is the softest and most formable of the commercially pure titanium grades 1 to 4. The material offers high ductility and good corrosion resistance. It is of particular interest when formability and corrosion behaviour are key considerations in the choice of material.
Grade 2: Higher strength combined with good workability
Grade 2 titanium has a higher strength than Grade 1 whilst retaining good ductility and weldability. This combination makes it a widely used pure titanium grade for industrial applications where mechanical strength and corrosion resistance are required.
In the case of powder-based components, the properties actually achieved also depend on the quality of the powder, the process control and the post-treatment.
Particle sizes and powder properties
The following characteristics are particularly relevant for processing in additive manufacturing systems:
- Grain size ranges: Typical size fractions are 10–45 µm, 15–45 µm, 20–53 µm, 45–90 µm or 63–120 µm. The choice depends on the specific process and the plant.
- Particle shape: A grain shape that is as spherical as possible promotes free-flowing properties and ensures an even application of the powder.
- Chemical composition: Compliance with the specified element limits is crucial for the material properties.
- Consistent powder quality: A defined particle size distribution and traceable batch data support process validation.
Applications of Grade 1 and 2 titanium powder
Additive manufacturing and 3D printing
In the additive manufacturing using metal powders Suitable pure titanium powder enables the production of complex geometries and bespoke components. It is crucial to tailor the titanium grade, grain size distribution and processing parameters to the desired component quality.
Chemical Industry and Plant Engineering
Pure titanium is used for components subject to corrosion in plant and equipment engineering. Corrosion resistance must be assessed on the basis of the specific medium, its concentration and the operating temperature. Powder-based processes open up additional possibilities for component geometries that are otherwise only feasible through complex manufacturing methods.
Medical technology
The biocompatibility of pure titanium makes the material suitable for medical and dental applications. When using titanium powder for implants or instruments, the material quality, manufacturing process and documentation must meet the requirements of the specific application.
Aerospace
For selected components of the Aerospace Low density, corrosion resistance and workability are important selection criteria. Where higher strength requirements apply, it is also possible to Titanium alloy powder such as Ti-6Al-4V may be considered.
