Shape
memory alloys (SMAs) are metal alloys that have the ability to remember their
original shape and revert to a preformed shape when heated. These alloys are
typically made by casting, vacuum arc melting, or induction melting technique
with the combination of different metals. Some of the major types of SMAs are
nickel-titanium (nitinol), copper-based alloys, and iron-manganesesilicon
(Fe-Mn-Si). These alloys are primarily used in medical devices and implants.
Apart from biomedical, other end-use industries of SMAs include aerospace
&defense, automotive, and consumer electronics & home appliances.
Based on type,
the Shape Memory Alloys market is segmentednickel-titanium (nitinol),
copper-based alloys, iron-manganese-silicon (Fe-Mn-Si), and others. Nitinol
alloys are the most widely used type of shape memory alloys. These alloys are
extensively used in the biomedical industry. They show the characteristics of
pseudoelasticity, high fatigue strength, and biocompatibility.Copper-based
alloysare predominantly used in the manufacturing of valves, pumps, propeller
shafts, fasteners, electrical & electronic components, springs, chemical
processing equipment, boiler feedwater heaters, and heat exchangers.Fe-Mn-Si
has a lower melting point and is lower in cost than nitinol shape memory
alloys. The increasing application of Fe-Mn-Si alloys in construction and
advanced engineering is driving their demand globally.

Based
on end-use industry, the market is segmented into biomedical, aerospace
&defense, automotive, consumer electronics & home appliances, and
others. Biomedical is the largest end-use industry of SMAs, followed by
aerospace &defense. Biomedical utilize shape memory alloys in implantable
devices, bone staples vascular stents, guide wires, stents, orthodontic arches,
implantable active devices, surgical tools, dental implants, andbeds. Shape
memory alloys are widely used in biomedical industry due to their shape memory
properties, biocompatibility, super-elasticity, high ductility, and resistance
to corrosion. In aerospace &defense, shape memory alloys are utilized inactuators,
engine (turbine, compressor, inlet, burner, nozzle), winglet, aileron, fin,
rudder, elevator, stabilizer, fuselage, landing gear, wing, vortex generators. Nitinol
alloys are used owing to their low weight, excellent high-temperature
properties, high strength, and corrosion resistance.Shape Memory Alloys is also
utilized in automotive, consumer electronics & home appliances, and othersindustry.
Other industry includes construction, personal accessories, industrial
machinery and transport machinery.
The Shape
Memory Alloys market is studied for five regions, namely, North America, APAC,
Europe, Middle East & Africa, and South America. North Americaaccounted for
the largest share of the Shape Memory Alloys market in 2020, followed by APACand
Europe.The increase in the aging population and the prevalence of chronic
diseases have propelled the demand for life-saving medical implants. Decrease
in fertility rate and an increase in life expectancy rate increases the aging
population.Shape memory alloys are widely used in biomedical applications,
particularly in medical implants, owing to their biocompatibility. Nitinol are
widely used for medical implants owing to their characteristics such as kink
resistance, constancy of stress, high elasticity, and corrosion resistance. US dominate the market for shape memory alloys
increasing use in various end-use industries, such as biomedical, aerospace and
defense, automotive, consumer electronics & home appliances. APAC expect the
fastest-growing market for shape memory alloys owing to increase in demand from
China, India, and Japan.
The
COVID-19 pandemic in 2020 impacted the global economy, with the government
enforcing regulations and restrictions to minimize the spread of the virus.
According to International Monetary Fund (IMF), the world GDP growth rate in
2020 was -3.3% and projected to grow 6% in 2021 and 4.4% in 2022.Major
economies contracted during 2020: the US by 5.9%, Japan by 5.2%, the UK by
6.5%, Germany by 7%, France by 7.2%, Italy by 9.1%, and Spain by 8%.The
businesses are coping with lost revenue and disrupted supply chains due to
factory shutdowns and quarantine measures.The disruption in supply of raw
material resulted in price inflation of various raw materials, including
nickel, steel, silicon, and manganese.The global commercial aviation
industrywitnessed a significant decrease in demand for new commercial airplanes
and services, with delays in the purchase of new jets by airlines, slowing
delivery schedules, and deferment of elective maintenance. In China, almost
two-thirds of automobile production has been directly affected by its
industrial shutdown, which largely impacted their suppliers. Moreover, the
shortage of Chinese-made parts has had a heavy impact on global production.Due
to increase in COVID cases, dental elective procedures were postponed. This
resulted in the reduction in the number of dental patients opting for dental
treatments in hospitals and dental clinics.According to the American Dental
Association (ADA), the US witnessed a decline of 66% in dental spending in
2020. Around 32% of reduction in the US dental spending is expected in 2021.
