1mmx5mm Thermal Bimetals Strip 5J20110 For Spring
Application:This material is mainly used for automatic control devices and
meters (such as: exhaust thermometer, thermostat, voltage
regulator, temperature relay, automatic protection switch,
diaphragm meter, etc.) as temperature control, temperature
compensation, current limiting, temperature indicator and other
thermal sensing elements.
Feature: The basic characteristics of Thermostat Bimetallic is bending
deformation with temperature changes, resulting in a certain
moment.
Thermostat Bimetallic Strip expansion coefficient is different from
the two or more layers of metal or alloy along the entire contact
surface firmly bonded, having a temperature-dependent shape change
occurs thermosensitive functional composites. Wherein the higher
expansion coefficient of the active layer is a layer called a low
coefficient of expansion of the layer is named passive layer.

2-3kg. For coil wire, 25kg.
2. How can you pay for small sample amount?
We have account, wire transfer for sample amount also ok.
3. Customer do not have express account. How will us arrange the
delivery for sample order?
Just need to provide your address information, we will check the
express cost, you can arrange the express cost together with sample
value.
4. What's our payment terms?
We can accept LC T/T payment terms, it also depending on delivery
and total amount. Let's talk more in details after getting your
detailed requirements.
