Specifications of Spring Lock Titanium Washers
Spring lock titanium washers are precision components designed to
provide a secure fastening solution in various industrial
applications. Here are the key parameters for these washers:
1. Grade:
- Gr5(Ti-6AL-4V): This grade indicates the use of Titanium Grade 5,
which is also known as Ti-6Al-4V, a widely used titanium alloy for
its strength and corrosion resistance.
- Gr2, Gr7, Gr9, Gr12: These represent other grades of titanium
alloys with varying compositions and properties suitable for
different applications.
2. Size Range:
- M2-M64: This range covers small to large diameters for the
washers, allowing them to be used in multiple types of fastening
systems.
3. Color Options:
- Available colors include titanium (natural), green, blue, gold,
and black, providing aesthetic options for different design
requirements or for differentiation in applications.
4. Pitch:
- The pitch options are 1.0 and 1.25, referring to the distance
between corresponding points on adjacent coils of a screw thread,
which affects the rate at which the screw can be driven into the
material.
5. Features:
- Lightweight: Due to the low density of titanium, these washers
are lighter than those made from many other metals.
- Low Density: Complementing their lightweight nature, these
washers have a reduced mass without compromising strength.
- Good Acid and Alkali Resistance: They exhibit strong resistance
to corrosive environments, including acidic and alkaline
substances.
- High Corrosion Resistance: Titanium is naturally resistant to
corrosion, making it ideal for long-lasting industrial
applications.
- Excellent Mechanical Strength: Despite its lightness, titanium
possesses high mechanical strength, ensuring secure fastening.
- Good Thermal and Hypothermia Stability: They maintain stability
at both high and low temperatures, making them reliable across a
wide temperature range.
6. Certification:
- These washers comply with international standards such as ISO,
and environmental regulations like ROHS and SGS, ensuring quality
and safety in their use.
7. Finishing Options:
- To enhance corrosion resistance and appearance, finishing options
include yellow, blue, and white zinc plating, galvanized, HDG
(hot-dip galvanized), chromate, and Dacromet.
8. Applications:
- These washers are suitable for use in industries including
automotive, bicycle, motorcycle, and medical implants where
reliability and durability are critical.
The combination of these specifications makes spring lock titanium
washers a versatile and reliable choice for fastening solutions in
a variety of environments and applications.
