(2) Classification: powder metallurgy porous materials, powder metallurgy friction reducing materials, powder metallurgy friction materials, powder metallurgy structural parts, powder metallurgy mold materials, and powder metallurgy electromagnetic materials and powder metallurgy high temperature materials. It includes: the geometric properties of the powder (particle size, specific surface, pore size and shape); the chemical properties of the powder (chemical composition, purity, oxygen content and acid insolubles, etc.); the mechanical properties of the powder (loose density, fluidity) , formability, compressibility, packing angle and shear angle, etc.); physical properties and surface properties of the powder (true density, gloss, absorbing, surface activity, ze%26mdash; ta (%26ccedil;) potential and magnetic properties, etc.) ).
5. General term for all properties of powder metallurgy sub-process and performance powder. Powder properties often determine the performance of powder metallurgy products to a large extent.
A trekking pole is an assistive device used for outdoor sports such as hiking below the snow line.
According to research, the use of trekking poles during walking provides a number of benefits
during exercise, such as
Reducing pressure on the knee joint by 22%, providing adequate protection to the knee.

Suitable scenarios
1. Outdoor hiking and trekking
Choose a three- or four-section trekking pole with a straight handle and aluminium or carbon fibre poles.
2. Flat/field walking
You can choose professional walking poles with sloping handles.
The walking poles have different wrist straps from ordinary hiking poles, with full palm straps that can
be used to match the swing angle of the arm.
The three-section carbon fibre poles are easy to carry and are more popular.
3. Recreational hiking/everyday use
Two-, three- and four-section poles are available, depending on the need for portability. You can choose
from aluminium, carbon fibre or wooden poles.
